How to add Variance Column to Matrix

Hi Anonymous ,

You can create the measures as below to replace the original measures [Acct],[Balance] and [WAR]:

Acct Variance =
VAR _2022 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2022, 12, 31 ) ), [Acct] )
VAR _2023 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2023, 1, 31 ) ), [Acct] )
RETURN
    IF ( ISINSCOPE ( 'Table'[ProdDt] ), [Acct], _2023 - _2022 )

Balance Variance =
VAR _2022 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2022, 12, 31 ) ), [Balance] )
VAR _2023 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2023, 1, 31 ) ), [Balance] )
RETURN
    IF ( ISINSCOPE ( 'Table'[ProdDt] ), [Balance], _2023 - _2022 )

WAR Variance =
VAR _2022 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2022, 12, 31 ) ), [WAR] )
VAR _2023 =
    SUMX ( FILTER ( 'Table', 'Table'[ProdDt] = DATE ( 2023, 1, 31 ) ), [WAR] )
RETURN
    IF ( ISINSCOPE ( 'Table'[ProdDt] ), [WAR], _2023 - _2022 )

If the above one can't help you, please provide some raw data in your table (exclude sensitive data) with Text format, your visual Fields settings and your expected result with backend logic and special examples? It would be helpful to find out the solution.
