Your asymmetric drill down needs to expand the "Field1" measure when the respective "Set1" set is selected. How should the calculated field be coded?
Select an answer:
o IF [Field1]=[Set1] END
o IF [Set1] THEN [Field1] ELSE "" END
o IF [Set1] THEN "" ELSE [Field1] END
o IF [Field1] THEN [Set1] ELSE "" END
