Only in Set Analysis

[lucasx15]

Hi, everyone!

I have this expression: 

(Only({<DT_CALENDAR_YEAR={2022}>} $(vQtdeExaDiarys))-Only({<DT_CALENDAR_YEAR={2020}>}$(vQtdeExaDiarys)))
/
Only({<DT_CALENDAR_YEAR={2020}>} $(vQtdeExaDiarys))

I have this expression: But my account is returning null value. Is the way to use a variable (vQtdeExaDiarys)  in Only correct?

Hi, hard to say without knowing what vQtdeExaDiarys stores, if it's a field name and that field has only one possible value it might work, in other case probably not.
