I'm trying to assign an Investment Program Position ID in the IO master data which have Budget amounts (from KO22) and actual postings. I'm not allowed to assign it because an error message appears "Order xxx is already budgeted or availability control is active". I've already deactivated availability control via KO32. I tried deleting the budget amounts in KO22 but I'm not allowed to because of the error message "Order xxx budget exceeded". What can I do so I could assign an IM Position ID to the IO?
