Aggregate non-matching values

Thanks lbendlin 

Hi, raprabhakaran 

Have you solved the current problem? Based on the sample data you provide and the output you expect, I do this by the following method:

LegacyTable

NewSysTable

I've created two measures as follows:

column1 =
VAR _id =
    SELECTEDVALUE ( LegacyTable[Row_ID] )
VAR _column1_of_LegacyTable =
    CALCULATE ( MAX ( 'LegacyTable'[Column_1] ), 'LegacyTable'[Row_ID] = _id )
VAR _column1_of_NewSysTable =
    CALCULATE ( MAX ( 'NewSysTable'[Column_1] ), 'NewSysTable'[Row_ID] = _id )
RETURN
    IF ( _column1_of_LegacyTable = _column1_of_NewSysTable, 0, 1 )

column2 =
VAR _id =
    SELECTEDVALUE ( LegacyTable[Row_ID] )
VAR _column2_of_LegacyTable =
    CALCULATE ( MAX ( 'LegacyTable'[Column_2] ), 'LegacyTable'[Row_ID] = _id )
VAR _column2_of_NewSysTable =
    CALCULATE ( MAX ( 'NewSysTable'[Column_2] ), 'NewSysTable'[Row_ID] = _id )
RETURN
    IF ( _column2_of_LegacyTable = _column2_of_NewSysTable, 0, 1 )

I put these two measures and the Row_ID columns of LegacyTable into a table visual, and the result is as follows:
