We use BW 7.5 SP06
I created characteristic ZCALQUART by copying 0CALQUARTER.
The problem is in BEX the offset on variable of ZCALQUART works only in interval one YEAR. For example variable "XXX" get value 2.2018 if I put: "XXX" - 1 it works and show 1.2018 but if I put "XXX" - 3 it does not work.
If I do all that manipulations with variable on 0CALQUARTER it works.
Please help to find solution, maybe I must do some additional tunning with my ZCALQURAT characteristic?
