Direct Query Date Conversion in DAX - Performance Issues
As per my company's Security team's risk evaluation, I have to create most of my deployed Power BI apps using Direct Query. My source data contain multiple dates, and are all read in from the source ...
This date table solution didn't seem to work for performance, but that could have been due to other constructions in my report, so I've decided to split the report into functional sub groups, in this way one report becomes many, which isn't ideal, but the populations are about 1/5 what the total report was originally. I sacrificed scope for run time.
DATE function (DAX) - DAX | Microsoft Learn says for the DATE function, "This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules." and I'm using this in a calculated DAX Column.
