Down Payments
Purpose
The purpose of this page is to explain the concept of down payments in Purchasing
and Logistics Invoice Verification areas.
Overview
This document states the business purpose of down payments in Purchasing and
Logistics Invoice Verification areas, and an example case of setting up and running
one cycle.
What is Down Payment?
As the name indicates, down payment is the initial upfront portion of the total amount
due. This payment is made during the onset of the purchase of an expensive
good/service.
In order to work with down payment, the switch MM_SFWS_CI_01 (business
function LOG_MMFI_P2P) should be active. This is available with SAP
Enhancement Package 4 for SAP ERP 6.0.
Down Payment Clearing
Down payments can be recorded in purchase orders and during Invoice Verification.
The down payment clearing function clears the down payments that have not been
cleared in FI. The system posts a down payment clearing document along with an
invoice document.
Down payment data can be recorded at both header level and item level of the
purchase order document. This data is copied to the financial accounting as default
values, and can also be changed depending on the need.
Note that if payment is added at header level, header data cannot be
distributed to line item data.
This is due to the fact that the down payment on header level is not split onto
the item level, it is retained at header level as a payment on the whole PO.
Header level in the purchase order:
Item level in the purchase order:
Technical field names:
DPTYP: Down payment Indicator
DPAMT: Down Payment Amount
DPPCT: Down payment percentage
DPDAT: Down payment Due date
Tables on purchasing: EKKO and EKPO.
Example of a complete down payment cycle
1. Create a purchase order with down payment data at item level (transaction
ME21N):
You can use the Business Add-In Enhancement for processing the purchase order
(ME_PROCESS_PO_CUST), to define the purchase order value as of which down
payments are mandatory.
2. Check the down payment monitor via transaction ME2DP. Observe the red
indicator suggesting down payment does not exist. This turns to green when a down
payment request or down payment is created:
We can create down payments through this monitor. The below path takes you to
the transaction FPDP_CREATE:
3. Create down payment request:
System adopts the down payment amount and due date from the purchase order,
but this can be modified if necessary:
Fill the header data, overview data, and choose Save button:
4. Check the purchase order history, because the down payment request gets
updated there (following the EKBE table results):
5. Create a down payment via ME2DP transaction:
6. Check the purchase order history (transaction ME23N):
7. Down payment clearing in transaction MIRO:
The DP clearing can be performed during the invoice verification process only when
the message M8318 is activated to be issued in the system. This message can be
controlled via the customer BAdI MRM_DOWNPAYMENT.
8. Choose the Down Payment Clearing button:
9. The next screen shows the down payment document number against which
settlement will take place:
10. Enter the down payment amount that needs to be cleared:
11. When posting the invoice, down payment clearing document is posted as well.
12. Display the invoice to see two accounting documents:
