I am migrating SSRS report into Power BI, i am facing below challenges for the drill down & drill up format and another is spliting column headers based on measure values. For the second screen shot when i drag and drop the one column header it is not showing the specific columns for example in my case 4 measures, it is taking all the 12measure values into it. I want to split into 3 Column headers*5 Columns=15
I can't get something useful from your snapshots, can you please share some detail information?
In addition, you can also take a look at following blog about get current row contents.
