hi,
I am getting the previous month value using variable PeriodN....with below formula
=FIELDVALUE('PeriodName', FIELDINDEX('PeriodName', ONLY(PeriodName))-1)
And in expression
Sum ({$<PeriodName={'$(#PeriodN)'}>}Values)
Is any other possibility to bring the values using the functions fieldvalue,fieldindex in an expression statement itself to find the same sum of values.
without using variable and assigning it,,,
