问题
My report has several pages showing data of a survey. I have various metrics, each fetching data from different/individual tables. All have filters applied on "key" column, as it should "not be null".
Everything works fine on power bi service, except one matrix for which the key filter automatically resets to "all" instead of "not null" upon publishing to Power BI service.
Any sort of help will be appreciated.
