I am developing user-exit that should move due date when it falls into weekend and holidays.
I am looking for solution to prevent inconsistancies between SD moudle and IF module.
Our invoices can origin from FI but also SD.
We want to include user-exit in some function-module that is used in SD and also in FI to calculate the due date.
I found FM DETERMINE_DUE_DATE but I want to be sure that moved due date will be the same across whole system.
