Example: Overpayment/Underpayment The following example illustrates payment postings and updates that have different amounts to the items to be cleared. They are overpayments and underpayments (partial payments).
Posting an overpayment or underpayment creates an amount split:
If there is an underpayment, the divided amount is in the invoice document to be cleared. One item maps the partial clearing and the other the outstanding receivable. In the payment document, the underpayment is posted as full clearing of the partial amount with the FM category
C
(clearing)
and is updated in the assigned FM account assignment.
If there is an overpayment, the divided amount is in the payment document. An item maps the full clearing of invoicing and is updated as FM category
C
(clearing)
in the assigned revenues FM account assignment. The remaining amount is posted as a payment on account with FM category
G
(payment on account).
Note
However, payments on account are only updated in
Funds Management
if you have activated the
Payment Matching
there. In the SAP standard system, payment on accounts are not updated in
Funds Management.
(See the Customizing for
.
The example below depicts an overpayment. The payment amount
(300)
is divided into a clearing amount
(-200)
and a payment on account
(-100)
. In
Funds Management
, the payment matching is activated, therefore the payment on account is also relevant for the update. The derivation rules are also defined so that the settlement payment and the payment on account are in different FM account assignments.

For simplification, the figure illustrates only one payment document.
