    Hi,

    Just in case you want to solve this without creating a relationship between the 2 Tables, write this calculated column in Table2

    Column = if(ISBLANK(LOOKUPVALUE(Table1[Records],Table1[Records],Table2[Received])),"No","Yes")

    Hope this helps.

Hi Anonymous ,

The RELATED function requires that a relationship exists between the current table and the table with related information. You specify the column that contains the data that you want, and the function follows an existing many-to-one relationship to fetch the value from the specified column in the related table.

In your case, the relationship between the two tables should look like the following picture, Table B on the one side, Table A on the many side:

If it doesn't meet your requirement, kindly share your sample data if you don't have any Confidential Information.

    Joey, below is an example of the tables content and along with the results in the (New Column) I would like to achieve.  Honestly, if there is a DAX comparison script which will compare each table column and if the content matches place a "Yes" or "No" in the new column.

     

     

    Table A		           Table B	
Records		         Received	          Match (New Column)
UKIM20010437411		UKIM20010211536	           Yes
UKIM20010442352		USIM10017106447	           No
UKIM20010232566		UKIM20009858062	           No
UKIM20010457623		UKIM20009867850	           No
UKIM20010201394 	UKIM20009903817	           No
UKIM20010211536		UKIM20010300727	           Yes
UKIM20010257629		UKIM20009939100	           No
UKIM20010300727		USIM10017308948	           No
UKIM20010396426 	UKIM20010437411	           Yes
UKIM20010411295		UKIM20010442352	           Yes
UKIM20010179221 	UKIM20010232566	           Yes

        Thank you - Dumb Question, what is the benefit of having the relationship between the 2 table in achieving the "Yes" or "No" in the new column?

         

        Your help is Much appreciated

      Hi Anonymous ,

      In my file the DAX code works fine, you can check if a relationship is created between the two tables.

      Because the row contexts and relationships do not interact in any way, so If you want to access columns on the one side of a relationship from the table on the many side of the relationship, you must use the RELATED function.

      Here is a demo, please try it:
