Paginated report embedded for your customer, RLS and CUSTOMDATA()
Hello, I'm using Power BI Premium and additional web application with its own authentication. I have published Power BI report and I am using service principal to communicate Power BI service wit web application. I am passing a parameter from web app to PBI service to know, who is logged in and I am reading that information using CUSTOMDATA() for RLS purposes. It works perfectly well. However, I have published Paginated Report with very same set up and it turned out CUSTOMDATA() retreives null, USERPRINCIPALNAME() and USERNAME() both retreive my login as a report publisher for each logged in user and built in (native) Report Builder function UserID retreives the same string for each logged user as well (it may be my GUID). Question: How to retreive in Paginated Report who is logged in to web app? How to get the same information like CUSTOMDATA() in Power BI but in Report Builder? Thanks
