In SAP FI, you can also post partial payments from the customers. These partial payments are posted as separate open items.
Customers can see clearly what all invoices have been issued to customers and what payments he has made. But it keeps the multiple open items, until the invoice is fully paid/ cleared.
Example − There is a customer with an outstanding amount of 1500 and he makes a payment of 500 as partial payment, then there will be two separate open items of 1500 Debit and 500 Credit in the FI system and no clearing document will be created.
T-code − F-28
Once you click on Process Open Items → Go to Partial Payment tab and select the invoice for which partial payment is done and the amount.
Click the Save button to post the document.
