I'm trying to use TMVL to calculate previous months.
VAR_FCMNTH = VARV(ZFORMNTH).
VAR_PRVMNTH = TMVL(VAR_FCMNTH, -COUNTER).
This never works because I always get the error:
'TMVL function only works for time characteristics of the area'.
I suppose here also it works on SAP provide time characteristics like 0FISCPER, 0CALMONTH, etc and not on custom characteristics like ZFORMONTH?
