Use
A partial payment is a payment that is posted to an account without any open items being cleared. You assign this partial payment to an open item. When you post the partial payment, the system marks the document number of the original open item in the line item for the partial payment. The original open item and the partial payment remain open.
Procedure
To enter a partial payment, proceed as follows:
Result
The system stores the document number, fiscal year and number of the invoice item in the partial payment. You can find this information in the Payment for field. Thus you can refer to the original open item from the partial payment. When you post the remaining amount for the invoice, both the partial payment and the invoice are cleared.
You can enter partial payments using the mouse. The advantage of this is that if the remaining amount has to be assigned to a single item, you can enter it automatically on the partial payment screen. To do so, place the cursor in the Payment amount field for the line item required and choose the item. The system then takes account of the difference for this item.
