Ill write about that in another post. Often it is necessary to connect Power BI to a data source that is hosted in an on premise environment. However, if you have many queries and you want a way to get Read more about Exposing M Code and Query Metadata of Power The mixed-mode of the composite model means that the fact table in our example is NOT LOADED into Power BI. This method can be used a lot in real world Power Query scenarios. You can simply use this file to access to the whole code behind of Power Query component of your Power BI solution. Doing concatenation in DAX is definitely good and useful. So what is the Dual mode? On the other hand many times you get multiple columns and want to change it to name, Read more about Pivot and Unpivot with When I import/read XML files FROM FOLDER , they sometimes have different culture versioning. Targeting SAPs ecosystem of developers and customers, Graphs one API and Business Data Graph reduce the cost and complexity of creating and deploying reusable extension applications. However, if you have many queries and you want a way to get Read more about Exposing M Code and Query Metadata of Power BI (PBIX) File[] 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!.

I am referring below link for desktop to achieve that functionality but once published dashboard, its not working. To convert this text to a date format we need to bring a Year value in the query. One of the main benefits of Parameters is that you can use that in a URL. Where could I find the calculated field expressions and measures field expression in the PBIX file? they might cause stopping the folding to happen. Here I explained a bit about how you can have the fiscal calculation Click on Table 0, and from Add Column menu option, click on Add Custom Column. For other tiles (where refreshing with the dataset refresh is enough) the values are based on import data. There are two transformations that are used very often for this purpose: Remove Empty and Remove blank rows.

Weve created a service that can be scheduled to do this job automatically. Hi Reza You can have bigger storage or compute power if needed. The main benefit of having a query to run by other queries is that you can repeat a number of steps on the same data structure. In Power Query, you can use Merge to combine data tables together. And if the new mixed mode model cannot be published to the Web Service, then it renders the facility largely redundant. Hi, I have recently discovered the benefit of using Direct Query mode.

The sample dataset I use for this example is the AdventureWorksDW2012 Excel file, which you can download it here. 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. Hi Susant, 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. Although there are some custom visuals for building a calendar, however, custom visuals come with some limitations sometimes. In future posts Ill go through steps of exploring data from the XML content in DataMashup file and also explain other files under *.pbix file. Well, thats the question I want to answer in this post. If you click on a blank area of a cell with Table hyperlink, you will see the table structure below it. Why doing concatenation in Power Query rather than DAX. Thanks a lot.
