    Hi aghonaim,

     

    Sorry. Recreate it as a calculated column.

Only thing i see your formula is missing to work is a MAX call:

 

LY = Calculate(AVERAGE(Table[Value]), FILTER(ALL(Table), Table[YEAR] = MAX ( Table[YEAR] ) -1 ) )

    aghonaim,

     

    The total is showing LY value of 2012. Because you have used MAX in your DAX. so, it picks Max(Year).

     

    Just Create a calculated measure with following formula,

     

    Last Year = LOOKUPVALUE(Table3[Value],Table3[Year],Table3[Year]-1) 

     

    you will get the required Value.

     

    Thanks,

    Siva

      I got this error:

      A single value for column 'Year' in table 'Table' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result.
