Paginated Reports Query

[Learn_PBI]

Hello All, 

I have created the paginated report, and the visual is table which have columns from different tables and no aggragate column is used as columns only few stings based columns are there, when I run it, i gives 1st error as given below and second error is when i remove blank values from column it gives second error.

I am using PBI dataset as data source.

If i use the some aggregation column in the end it works.

Please guide me with this.

Thank you in Advance

If you are pulling in columns from multiple tables you should always include a measure otherwise you will just get a crossjoin of every possible combination of all the values which is not typically. You don't need to include the measure in your visualization, but having it in the query will allow the engine to correctly resolve the joins between the various tables.

I tried using a measure at the end in dataset, still same 2nd error

Can you try limiting the amout of data, put a Top N clause to see if this is because you are pulling too much data with your query? Also, you might have more information in the log file that could help diagnose. The file is at C:\Users\(you)\AppData\Local\Microsoft\Power BI Report Builder\15.7\Traces

This is the code which got generated with in-built functions, I tried using top N, but the query is not getting validated.

Please guide me if i am missing anything.
