Comparing two tables
Hi All,
I have 2 tables, Table 1 and Table 2 , Both has different structure and i am trying to find the list of users from table 2 who are not in table 1. I have merged the tables, but unable to figure it out. Any help would be highly appreciated.
Thanks,
Pinky
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.
