I have a created a variable in the webi report as follows :

=NoFilter(Sum([ABC]) In ([DEF)]

For this variable I have values as follows :

12345

45678

91011

then I wan to apply total sum on these values, the final result will be 149034 which is correct.

But I am getting wrong result in XIR4.1 where as in XIR2 i am getting the corrcet result

Please help!!
