    Hi HarsimranPWRBI 

    Try this. Note that you were using Cateogry in the definition of table1 and Category when referencing the column in table H

    DEFINE
    VAR table1 =
        UNION (
            ROW ( "Cateogry", "A", "Value", INT ( 1 ) ),
            ROW ( "Cateogry", "A", "Value", INT ( 2 ) ),
            ROW ( "Cateogry", "A", "Value", INT ( 3 ) ),
            ROW ( "Cateogry", "B", "Value", INT ( 4 ) ),
            ROW ( "Cateogry", "B", "Value", INT ( 5 ) ),
            ROW ( "Cateogry", "C", "Value", INT ( 6 ) ),
            ROW ( "Cateogry", "c", "Value", INT ( 7 ) )
        )
    --EVALUATE table1
    VAR H =
        SUMMARIZE (
            table1,
            ROLLUP ( [Cateogry] ),
            "Sum of Value", SUMX ( table1, [Value] ),
            "Max of Value", MAXX ( table1, [Value] ),
            "Average of Value", FIXED ( AVERAGEX ( table1, [Value] ), 1 )
        )
EVALUATE
H

    Hi AlB ,

     

    Does that mean only Iteration function can be used to refer column for aggregation?

     

    Thanks,

    Harry

      If the table is "dynamic", or "virtual" (you create it within the code),  you cannot reference the column in the usual way as with "actual" existing tables, you have to go with

      SUMX ( VirtualTableName, [ColumnName] )

      vs the usual  

      SUM ( ActualTableName, ActualTableName[ColumnName] )
