HI Pinky0404
There are a few ways you can do this.
In DAX you can use the EXCEPT function to generate that as a list.

You can create this a as a calculated table if you prefer something like,
New Table = EXCEPT( SELECTCOLUMNS(TableA , "UserID" , [UserID]) , SELECTCOLUMNS(TableB , "UserID" , [UserID]) , )That approach will give you a list of Users that appear in TableA, but don't appear in TableB
Otherwise try a Left outer join in Power Query.

You can try using a Left Anti merge, starting with Table 2. This will show you records that exist in Table 2 that do not exist in Table 1 based on whatever field relates the two tables.
