Complete allocation structure ZM
Message no. KD503
During settlement, the system puts the sender debits into groups (assignments), which are settled using the same settlement cost element. The settlement assignment is made in the allocation structure, which is stored in the settlement rule for the sender (under settlement parameters).
Cost element 630050 cannot be assigned to a settlement cost assignment in allocation structure ZM, and therefore it cannot be assigned to a settlement cost element.
Possible solutions are as follows:
If the posting under cost element 630050 was made to the sender because of an incorrect entry, and you can reverse the posting, and do not need to update the allocation structure. You only need to reverse the incorrectly assigned posting before repeating the settlement. Exception: For an investment measure with a line item settlement, you need to extend the allocation structure, even after the reversal.
If the posting was made correctly, you can do the following:
a) You can assign a different allocation structure to the sender: In the master data maintenance for the sender, choose "Settlement rule -> Goto -> Settlement parameters" and then enter a different allocation structure.
If necessary, also check whether the correct allocation structure is entered in the settlement profile. The allocation structure is defaulted in the settlement profile when you create sender master data or when you maintain the settlement rule.
You can update allocation structure ZM
