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
| 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.

You can use TREATAS to bridge the air gap between tables if they have equivalent sets of columns.
