Setting up row level security with lookupvalue
Hi all, I'm relatively new to DAX expressions and my head is spinning a little bit so hopefully I can get some clarity here. Say I have two tables: Table_1 Grade Year Month SchoolID 11111 33333 22222 44444 Table_2 Email IdentityID SchoolID [email protected] 10 11111 [email protected] 10 22222 My report consists only of data in table_1. When logging in to access the report, a user may log in with their gmail or hotmail account and will access the same data, rows from Table_1 where SchoolID IN (11111,22222). In Power BI, I'm trying to create a DAX expression that will get the identity ID from the UserPrincipalName, get all SchoolIDs that match that IdentityIDs, and show all rows from Table_1 that have SchoolID in that list of SchoolIDs. I tried playing around with LOOKUPVALUE but since that only returns a single value, I'm not sure if that's the right track.
