He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. However, if the concatenation is coming from a big number of items in the list, and there is no need to do the concatenation dynamically using a measure, then Power Query would work faster from the end-user point of view, the main reason is that you do the concatenation in Power Query BEFORE loading the data as a pre-calculated value. Reza is an active blogger and co-founder of RADACAD. This feature is called Analyze in Excel and I explained it here. you will see some binary things first (which are related to the zipped nature of this file), and also some XML information. He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. Remove Empty in Power BI and Power Query. Well, thats the question I want to answer in this post. WebA Power BI report is a visualization element connected to an in-memory dataset behind the scene (I am talking about the most common method of using Power BI; Import Data). Thats the work done by a generator function. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user groups. The composite model can even go one step further in the performance when aggregations are used. He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. Parameters are ways to pass values to other queries. Hello Reza, He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user Finding rows that are in one table, but not the other is one of the most common scenarios happening in any data related applications. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user If that doesnt work for you, then this is another approach that I use a lot myself. If you want to make modifications in function, you can simply modify the main query (which is Table 0 Example). Lastly I removed row 5 in table B. It depends on the source, and the transformations. If you dont want to use slicer and you want to use normal visuals for filtering down, then you can control the Interaction simply, here is how: Hi Ramani. https://radacad.com/control-the-interaction-in-power-bi-report, Thank you once again for reply but this is not what I am looking. Is there something like a full-Anti Join? For some scenarios, there is an advantage in using Power Query to do the concatenation. That means you dont need to enable it anymore in the options. My concern is that it remains spinning to load about 46 millions of row which is the size of the table in the original format before applying all the steps that I did in the power query and at the end when I go to the Data view in the Power BI Desktop my table has only 600,000 rows. There can be many reasons that cause the load process to be slow, here are some: complex data transformations, the volume of data (rows and columns), the data source itself (excel file, database, etc) With recent updates of Power BI Desktop, creating custom functions made easier and easier every month. One case Im working on is finding the differences between 2 tables. And these two joins alone dont get me the right result. Doing concatenation in DAX is definitely good and useful. You mentioned that it becomes even slower after putting a filter. He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. With Graph, developers access SAP-managed business data as a single semantically connected data graph, spanning the suite of SAP products. files with *.m extension. Hi Ashish, One of the ways to speed up the performance is to get the smaller part of the data, only the part that is needed for analysis. Having a DirectQuery connection means that some of the functionalities I explained here might not work for you, because Power Query transformations are limited when it comes to the DirectQuery mode. Power BI Datamart is more like a container around other components of Power BI (Dataflow, Dataset, and Azure SQL Database). Sample Report Page. The refresh works perfectly fine. Often it is necessary to connect Power BI to a data source that is hosted in an on premise environment. Composite Model means now you can have a model, that very large tables of that are coming from the DirectQuery connection, without the need for importing, and small tables to be imported to be accessible quickly. Sample Report Page. When you have blank values in your data table, you can use Power Query transformations to remove the row with blank values. To learn more about Power BI, read Power BI book from Rookie to Rock Star. Cheers Power BI Datamart also comes with a unified editor in the Power BI Service. This feature is called Analyze in Excel and I explained it here. In Power BI Desktop, after loading the table, you can see on the right-handside bottom corner, that we are using the DirectQuery storage mode; Now for the second table, I get data from Excel. WebHe is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress.

In the previous article, I explained how you can build a data model for budget vs. actual, where the grain of the two fact tables is different. Reza. WebPower BI calendar visual Power BI doesn't have a built-in calendar visual. If you create a calculated column in an Import table or a calculated table, then there will be no limitation. 3- number of characters The storage mode can be; Import, DirectQuery, or Dual. But unlike Import Data, there is a copy in the memory, and there is still the main table in the DirectQuery source. Hi, this sadly wont work in combination with a power bi dataflow as other datasource any experience with this? So what is the Dual mode? The dimension, however, is already importedinto the Power BI model and needs to be refreshed time by time. For example, many of these queries are not loading in Power BI and disabled for load. In the email inbox above, you see two emails each day, because I have scheduled two files to be snapshotted and sent to me. so you have to use DirectQuery. Through an example Ill show you how to create a custom function. Many thanks All happened here is that there is a copy of the Table 0 query created as a function. Reza Rad is a Microsoft Regional Director, an Author, Trainer, Speaker and Consultant. We can do that for one of the years (doesnt matter which one). Power BI date table m code. Now, using this feature, you can have part of your Power BI dataset connected directly from a data source, and another part to be imported. What you want is possible through the Power BI visuals and slicers itself. The snapshot can be created in other formats and stored in other locations too. Is it still working for you in March 2020 update? To learn more about Power BI; read Power BI book from Rookie to Rock Star. If it was a database system or something that would have supported query folding, it would have even become faster. Reza Rad is a Microsoft Regional Director, an Author, Trainer, Speaker and Consultant. Awesome! Cheers Not in the top section change the From Web window to Advanced. Although there are some custom visuals for building a calendar, however, custom visuals come with some limitations sometimes. Power BI date table m code. Read: Power bi calculated column vs measure. I have a PBI-Desktop report connected to Azure Cosmos DB, using the URL and Primary key. I have written a lot about Power Query M scripting language, and how to create custom functions with that. WebPower BI reports can get slow if you have huge amount of data. In my previous article and video, I explained why DirectQuery for a Power BI dataset is an important feature.In this blog and video, I explain how this feature works step by step. Calculated tables are available in the composite model. We maintain Our Fiscal Year start and end date in a seperate table. This ensures that you get the best performance when working with smaller tables (such as dimension tables) in a dual storage mode. Merge can be also used for finding mismatch records. by using direct query we have lot of limitations.so could you please suggest better approach to do this. The reason is that you are getting the entire table without any filtering or transformation. And if the new mixed mode model cannot be published to the Web Service, then it renders the facility largely redundant. I believe your inquiry can be done with Merge (or every maybe append depends on the structure) and some conditional expressions. For some scenarios, there is an advantage in using Power Query to do the concatenation. and all happened through GUI. but before that, lets see how from a sub-table, you can get only one column of it: The sub-table of subcategories that you see in the above screenshot, has two extra columns. Thanks a lot. In my previous article/video, I explained how you can hide sensitive data from the users view. I need a function to change the TextEncoding.Utf8. Most of the time, you want to analyze only part of the data, and that part of the data has something to do with the dates. In the Invoke Custom Function window, choose the function (named GetHolidays), the input parameter is from the table column name Column1, and name the output column as Holidays. He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. Reza, thank you for this beautiful article. WebPower BI enables you to connect to the model published in the Power BI Service using Excel. depends on the situation there might be some workarounds. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user Power BI Dashboards for DirectQuery data sets refreshes every 15 minutes. Reza. For some scenarios, doing it in Power Query speed up the process, especially if the concatenation doesnt need to be dynamic and can be pre-calculated. If you have a visual that has columns from Import tables and a dual table, then the dual table will act like an Import. Cheers Reza is also co-founder and co-organizer of Difinity conference in New Zealand. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user groups. Why doing concatenation in Power Query rather than DAX. Generators are a topic of its own and cant be discussed in this post. To implement this, here is the below steps: Step-1: First, we have to create a table and enter a start date. It will come to service for sure. Because sometimes measures are using nested functions and tables, the whole process of debugging DAX code becomes the two customer tables and the order status? Reza. Often it is necessary to connect Power BI to a data source that is hosted in an on premise environment. You might only Read more about Only Get the Last Few Periods of Data into Power BI using Power Query Previously, when you used DirectQuery, you couldnt even add another data source into the model. For now, lets focus on DataMashaup File. There have been numerous (at least 3!) In your Query Editor Window, create a New Source from Home tab, and choose Blank Query. With this feature, you can also leverage the option for using Dual storage mode to keep a copy of a DirectQuery table in memory for answering quick slicing and dicing questions. With a Custom function you are able to re-use a query multiple times. Doing concatenation in DAX is definitely good and useful. Power BI Datamart also comes with a unified editor in the Power BI Service. I believe the data source is something that doesnt support query folding then. Starting binary data are related to the zipped nature of this file (which weve already went through it in previous part of this post). It is always easy to open a PBIX file and realize the queries in Query Editor Window. lets look at that. How can I fix this? as expected it takes a while to load the data (a couple 100records a second) but when I would filter on a date field in the query it takes even longer! Click on Manage Parameters menu option in Query Editor, and select New Parameter. User with resharing; In addition to being the user, this user can also reshare this data source with other users. Reza, Hi Reza, very interesting post! Reza, Salam Reza, How can I filter a column formatted as date to the latest two dates? You will learn through this blog post, how in Power Query you can find out which records are missing with Merge, and then report it in Power BI. To learn more about Power BI, read Power BI book from Rookie to Rock Star. In a monthly analysis of the data, the FactResellerSales has values for each month, but because the other table doesnt, then the calculation of budget vs. actual would be wrong in every month, for the first month, the budget value is so high (because it is for How DirectQuery to Power BI dataset works. When you have blank values in your data table, you can use Power Query transformations to remove the row with blank values. third part of URL is the remaining part after the year which is: altogether these will make the URL highlighted above which instead of {Year} it will have 2016, or 2015 or other values. However, if you have many queries and you want a way to get Read more about Exposing M Code and Query Metadata of Power Before understanding how this feature works, I recommend reading below to understand WHY Most of the time, I have seen models that have many tables all related to each other with bi-directional relationships, and hence; the performance problem.Consider Star Schema design Seriously!. This Parameter later will be used as input of the query. You can also schedule part of data (as a table) to be exported to CSV files. this is just a preview at the moment in Desktop. We want the process to be dynamic, so if a new years data appear in that page, that will be included as well. However the field itself can be sorted based on another column. Considering the Composite mode explained above, you probably ask yourself this question where the data is stored in every table, and how they are working behind the scene? You will learn through this blog post, how in Power Query you can find out which records are missing with Merge, and then report it in Power BI. Using technologies such as Azure SQL Data Warehouse means you can use scalable compute and also storage for the data and also querying it. Read: Power bi calculated column vs measure. Using this option, you will be able to see the Data tab (which you couldnt have done in mere DirectQuery mode previously), and you can see only Import Data tables there. Prerequisite. If you change the parameter value and refresh the query you will see changes, but we dont want to do it in this way. Reza is an active blogger and co-founder of RADACAD. Both have geography table which contain State column. One way to check it is to run SQL Profiler and track the query sent to the data source, if that query is the unfiltered data, then query folding doesnt happen. By Default the source query (in this example named as Table 0 Example) will be loaded into the model. I am writing a blog series next week about aggregations and one of those is all about Dual storage mode. Sharing. In this example, you would find a couple of those join kinds useful; Left Anti Join, and Right Anti Join. Reza is also co-founder and co-organizer of Difinity conference in New Zealand. You can have bigger storage or compute power if needed. Reza. This started with bringing Parameters few months ago, and adding source query for the function in November update of Power BI Desktop. In 2018, Power BI added a breakthrough feature called Composite Model. The year value for this query can be statistically set to 2016. Composite Model in Power BI; DirectQuery and Import Data Combined, Power BI Architecture Brisbane 2022 Training Course, Power BI Architecture Sydney 2022 Training Course, Power BI Architecture Melbourne 2022 Training Course. However, if you have many queries and you want a way to get Read more about Exposing M Code and Query Metadata of Power If you have users who are using Power BI Desktop to create reports on top of your model, and they are going to create DAX measures, then there is a better and more This also comes with a new storage mode; Dual, which you will learn about it a bit later in this post. Reza is an active blogger and co-founder of RADACAD.

He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user groups. Reza, Very good blog. I will explain this part later. In this post, you will learn about the composite model; what it is and how it works. Weve created the ability to connect to the Power BI data model, and even export the data table into CSV files. But in version of power bi desktop July 2020, i didnt find the composite mode option in preview features in file > options. we might need to wait for a few more months This is also true in some cases of using on-premises technology, however, you Dual Mode is only an option for DirectQuery data sourced tables. WebPower BI Desktop file stores many metadata information in it, one of the most important piece of information stored there is Power Query M scripts. Then you probably want to apply same steps on all other pages for other years (2015, 2017, 2018), So instead of repeating the process you can reuse an existing query. As long as you slice and dice data in the level of granularity that both tables support, then you dont Read more about Budget vs. Actual Model in Power BI: Calculations and If I have 6 sales person and assigned one/two role(map to county) to every one based on different country. So Add another part, and put setting as below; Configuration above means that in the first part of URL we put everything before 2016 which is: http://publicholiday.co.nz/nz-public-holidays-, Second part of URL is coming from parameter, and we use Year parameter for that. which is an extra step, but still works fine. This feature is called Analyze in Excel and I explained it here. These two transformations are not This is also true in some cases of using on-premises technology, however, you These two transformations are not exactly the same. For me that is a reason to work with mixed mode. Hopefully somewhere in Europe next time This column would now produce a table in every cell, but this new table would have only one column: the EnglishProductSubcategoryName. This will open Query Editor Window for you, You can now make some changes in the query, For example remove the first column. Import and DirectQuery in the storage modes above are understandable enough. The method explained here is using a free API, if you use the method and appreciate the work done for it, you can buy a coffee for the creator of the API. so, Ill go through other parts of the structure briefly. This was really helpful, thank you! DirectQuery was not a common method when it comes to working with data in Power BI, especially because with this mode you couldnt combine multiple data sources, but with the composite model, the DirectQuery becomes faster. There have been many techniques for creating a data table On Power BI using DAX expression. Custom Functions Made Easy in Power BI Desktop, Power BI Architecture Brisbane 2022 Training Course, Power BI Architecture Sydney 2022 Training Course, Power BI Architecture Melbourne 2022 Training Course, Power BI online book from Rookie to Rock Star, blog post about Enable Load in Power Query, Warning! Reza. Here are some of the things to consider when doing data modeling with a Power BI composite model. If I want to compare 2 tables, see what rows are different from one another. He has a BSc in Computer engineering; he has more than 20 years experience in data analysis, BI, databases, programming, and development mostly on Microsoft technologies. The method I explained there is a simple method, however, for a specific type of user. If you like to learn more about Power BI; read Power BI online book from Rookie to Rock Star. The Dual storage mode, works as DirectQuery or Import Data, depending on what other tables related to it are used in a visualization. One of the main benefits of Parameters is that you can use that in a URL. However, when you want to expand the list, there are two items: Expand to new rows, Expand to New Rows, and Extract Values. Power BI Datamart Vs. Dataflow Vs. Dataset; Categories. But I believe very soon Hi Rick. If you have that many rows, it is better to make sure the Query folding happens. Hi. Is there any other ways that you want to filter your dataset but you dont know how to do it? Weve created a service that can be scheduled to do this job automatically. Thanks Adam. However, you do need to apply a bit more transformations. However the field itself can be sorted based on another column. WebA Power BI report is a visualization element connected to an in-memory dataset behind the scene (I am talking about the most common method of using Power BI; Import Data). Power BI reports can get slow if you have huge amount of data. Here is the actual Power Querys Query Editor list: all of these queries, parameters, and functions are in the section1.m file.

Arwen is a data analyst in a large enterprise and his company has a data warehouse and BI team. WebRemove Blank Rows Vs. [Content_Types].xml: explains the content of this section, very high level information. Previously (about a year ago), creating custom functions was only possible through M scripting, with lambda expressions, that method still works, but you need to be comfortable with writing M script to use that method (To be honest I am still fan of that method ). You have all you need in terms of understanding the metadata of tables, queries, parameters, and functions. Reza Rad is a Microsoft Regional Director, an Author, Trainer, Speaker and Consultant. Hi Youcef WebIn Previous section you learned about Power Query through an example of data mash-up of movies. Does it really load the 46 millions of row into memory then it applies all other filtration even though I did a Transform Data? Calculated tables will be refreshed at the scheduled refresh time of the Power BI dataset. For this example I want to create a list of numbers from 2015 for 5 years. Hi, Hi Saliya There are three options: Import, DirectQuery, and Dual. Click on Query1 in Queries pane, and in the Formula bar type in below script: After entering the expression press Enter and you will see a list generated from 2015 for 5 numbers. Reza is an active blogger and co-founder of RADACAD. then group by data by that new column, and then sort it descending and get the first item of each group. DataMashup: This is the file which is main topic of this blog post. In that case, it is better that you do your filtering/transformation in the SQL database itself using SQL queries and then load it into Power BI. In Power Query, you can use Merge to combine data tables together. I tried this last time with file saved with Feb 2020 update and it worked but now it does not. or . He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress.

You can concatenate a list of values in Power BI in two ways; Using Power BI DAX functions such as ConcatenateX, or through Power Query. The function itself marked with fx icon and that is the function we will use to call from other queries. You can use Table.SelectColumns Power Query function to achieve only the columns you want. This is for when we import the data into Power BI. To use this function, you can add a new custom column first; Then you can use the Table.SelectColumns function to only select the EnglishProductSubcategoryName. Small tables can be imported into Power BI for better performance. Hi Carel Tough Decision! This is not a new or advanced feature in Power BI. I have two data sources for customer orders. He is a Microsoft Data Platform MVP for nine continuous years (from 2011 till now) for his dedication in Microsoft BI. Analyze in Excel is a much better way to connect to the data model and extract information than exporting data because Analyze in Excel has a live connection to the Power BI dataset. WebGoogles stream analytics makes data more organized, useful, and accessible from the instant its generated. It MAY become later available for live connection too, but we dont have it yet. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user groups. By enabling composite mode I imported two power bi dataset into one Power BI desktop file. You have seen that you can change definition of function simply by changing the source query. Andrea, one way is to add a custom column in Power Query to each table with DateTime.LocalNow() and then use that for reporting. If you have users who are using Power BI Desktop to create reports on top of your model, and they are going to create DAX measures, then there is a better and more This function at the time of writing this post is only available through Power Query M scripting. However, for parameters there is a meta information: for functions; there is a FunctionQueryBinding section which explain where the function is sourced from; So, very easily you can access all queries pane from this area. The date is one of the most important factors for filtering your data. and every time you call this function with an input parameter (which will be year value) this will give you the result (which is public holidays table for that year). For example; you might have 20 years of transactional data stored in the database, but you only want to do an analysis of the last three years. Reza. Ankur, Hi Ankur WebPower BI reports can get slow if you have huge amount of data. Here is where Custom Function comes to help. And select DimCustomer from the Excel file (this excel file is the Excel version of the AdventureWorksDW database, you can download it from the link in my other blog posts). In Power BI Desktop, everything has a GUID assigned to it. What I always do is to use Transform Data (It was called Edit previously). Hi Cinna The mixed-mode of the composite model means that the fact table in our example is NOT LOADED into Power BI. Then you can choose dates in the Filter Rows section. There have been numerous (at least 3!) The rate at which Power BI is evolving to deliver is simply amazing. To implement this, here is the below steps: Step-1: First, we have to create a table and enter On the other hand many times you get multiple columns and want to change it to name, Read more about Pivot and Unpivot with It allows large-scale, complex and reusable data preparation to be done directly on the Power BI Service and store it Find Mismatch Rows with Power Query in Power BI, Power BI Architecture Brisbane 2022 Training Course, Power BI Architecture Sydney 2022 Training Course, Power BI Architecture Melbourne 2022 Training Course, What the Merge is, and what is the difference of that to Append, to know more about other types of joins, read this post, The Power BI Gateway; All You Need to Know, Incremental Refresh and Hybrid tables in Power BI: Load Changes Only, Power BI Fast and Furious with Aggregations, Azure Machine Learning Call API from Power Query, Power BI and Excel; More than just an Integration, Power BI Paginated Report Perfect for Printing, Power BI Datamart Vs.

When you see the data rows in Power Query Editor, you might think that the data is already loaded into the memory, and you want the filtering to happen beforehand. Is the query inside a group or not (highlighted red), or is it enabled load in the report (highlighted green), and many other information. Thanks for your kind words. Because sometimes measures are using nested functions and tables, the whole process of debugging DAX code becomes After doing all the transformation in Power Query Editor, when you click on Close & Apply, at that moment, the entire REMAINING data after filtering will be loaded into Power BI. Power BI Desktop file stores many metadata information in it, one of the most important piece of information stored there is Power Query M scripts. If you try to change the mode of an Import table to Dual, you see that this change is not possible. Especially when you expand you will see this behavior. He is also the author of very popular book Power BI from Rookie to Rock Star, which is free with more than 1700 pages of content and the Power BI Pro Architecture published by Apress. Remove Empty in Power BI and Power Query. The data stored in my Cosmos DB database tho, has changed over time and some fields have been added, but because of the 1000 rows limit of query editor while transforming the data that is being imported, PBI does not see the columns corresponding to the newer fields. Power BI Dashboards for DirectQuery data sets refreshes every 15 minutes. Now with this service, you can get any Power BI file in the service to be scheduled for snapshot the report/dataset, or even the data of it exported as CSV format. Cheers Where could I find the calculated field expressions and measures field expression in the PBIX file? Now, using this feature, you can have part of your Power BI dataset connected directly from a data source, and another part to be imported. However, if you have many queries and you want a way to get the script of all of them then this post is for you. I never use that option! For some scenarios, there is an advantage in using Power Query to do the concatenation. If you like to learn more about Power BI, read Power BI book from Rookie to Rock Star. Cheers However, this doesnt tell you the folder structure, or some other query editor settings. Power BI users Sorting in most of the visualizations, you can choose to sort ascending or descending based on specified data fields.

List Transformations in Graphical Interface of Power Query In Power BI Desktop also we have the Performance Analyzer now, which helps to find out which visual runs slower, and find out the DAX calculation for it, to be In this example our main query is the query that process the holidays table in every page, and return that in proper format of Date data type and Text for description of holiday. The method I explained there is a simple method, however, for a specific type of user. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user Power BI Datamart is a combination of Dataflow, an Azure SQL Database (acting like a data warehouse), and Dataset. Can we include import from PowerBI dataflows in composite model scenarios? Changes are fine as long as you dont want to edit the M script of the function, if you want to do so, then the function definition and the query definition split apart. Reza is also co-founder and co-organizer of Difinity conference in New Zealand. If you like to learn more about Power BI read Power BI book from Rookie to Rock Star. I am connecting to a Power BI dataset. Now we will see how to create a data table using Power Query M code. DataMashup file in *.pbix file included all you need to access to Query Editors metadata information, and also the M scripts. Remove Blank Rows Vs. A composite model in Power BI means part of your model can be a DirectQuery connection to a data source (for example, SQL Server database), and another part as Import Data (for example, an Excel file). Power BI Datamart is a combination of Dataflow, an Azure SQL Database (acting like a data warehouse), and Dataset. How many times you have been thinking to see is this possible to store the data of the Power BI report every day, every week or month. if you want to do this filtering based your fiscal year, you can go two years back, and then find the start of the fiscal year for that period (based on whatever logic calculated), and then filter everything after that. He is an International Speaker in Microsoft Ignite, Microsoft Business Applications Summit, Data Insight Summit, PASS Summit, SQL Saturday and SQL user groups. that is not an option yet, but I believe it is in the backlog and will come sometimes in the future. A gateway is a software component that resides on premise that can communicate with Power BI. Hi Johan SecurityBindings: I believe this is Row Level Security configuration in the Power BI stored in binary format. List.Accumulate is a function that loops through items of a list and applies a transformation. The two tables that I have in my datasets are DimProductCategory and DimProductSubcategory, I removed unnecessary columns, and here is the structure of tables: There are many different transformations that can lead to having a list of values. 2- you are in the Power BI Desktop environment, not in the Power Query Editor If you use Expand to New Rows, you will get one product subcategory in each row, which is not what we want. These two transformations are not There have been many techniques for creating a data table On Power BI using DAX expression. I have written a lot about Power Query M scripting language, and how to create custom functions with that. Having big data tables with the DirectQuery and smaller tables with Import Data is much better than doing everything pure DirectQuery, because in the pure DirectQuery mode, even for querying data from small tables, the performance would be still slow. This includes every single M script all in one place (as long as they are all under one section). This function at the time of writing this post is only available through Power Query M scripting. Great walk through of Composite Models. you can import from any data sources, dataflows included For this example, I used Merge transformation to create a structure like this: (merged the two tables based on ProductCategoryKey). Yes, this is a zipped file. for example, first, you need to fetch the Month and Year from the date field as a custom column. It was so easy. And reports need to run on daily base schedules. In Power Query, you can use Merge to combine data tables together. Do you have any suggestions? This started with bringing Parameters few months ago, and adding source query for the function in November He has a BSc in Computer engineering; he has more than 20 years experience in data analysis, BI, databases, programming, and development mostly on Microsoft technologies. All of these features are available for free, even now, when you use the Power BI Helper. Most of the times, a date condition is a good filter for that.
