Down Payment Request Process
A customer ordered some goods from your company. Since you are not sure about the customer's commitment, you request a payment advance from the customer by issuing a down payment request. You also use this document as a basis for other key steps in the sales process, for example, creating the final invoice.

Process
Create an A/R or A/P down payment request for the relevant business partner. If you do this by drawing a base document, verify that you have defined the required down payment percentage. For more information, see A/R Down Payment Documents: General Area or A/P Down Payment Document: General Area.
No posting is made at this stage.
Once the actual payment for the down payment request is made, create the proper payment document based on the down payment request. A down payment request can be paid in full or in parts.
NoteYou can use the payment wizard to pay the down payment request.
End of the note.After you create the payment document, a journal entry is recorded in the down payment accounts. If the down payment request was paid fully, the down payment request is closed. If it was only paid partially, it remains open for another payment. You can edit a down payment document that was only partially paid, provided that no rounding amount was specified on the document.
If only part of the down payment request was paid and you do not expect further payments on it, you can close the request by choosing

Close
. This closes the down payment request document and you are not able to record payment of the outstanding amount in the future for the closed down payment request.Create a regular invoice. You can copy the data from the base document drawn into the down payment request, for example a sales order, since it was not closed as a result of the drawing into the down payment request.
To link the down payment request to the invoice, choose
(Browse
), select the relevant document, and specify the net or gross amount to be copied into the regular invoice.You can specify a higher amount in the down payment request than in the invoice. This means that the total amount of the invoice will then be negative.
NoteYou can link a down payment request to an invoice only when you create the invoice. You cannot do this at a later stage, for example, when recording the payment in the Banking module or during internal reconciliation.
End of the note.After you add the invoice, SAP Business One creates the regular postings.
If there is still an outstanding balance due on the regular invoice after linking the down payment request to the invoice, you can create a payment. The table of the payment documents displays the invoice. Select the required document and continue to process the payment.
