Partial payment of customer retention

durward44 · ‎09-08-2023

Dear readers,

I am facing an issue where standard payment / clearing processes in SAP don't allow to partially pay customer retention using CGS.

Context :

- No issue to partially pay customer retention if the invoice is a "DR" document type made through FB70

- impossible to partially pay customer retention if the invoice has been made through SAP-SD module (t-code VF01) resulting in "RV" document type

- Customer retention postings are identified through special G/L key (09/19) and CGS code "H"

2 cases were studied to illustrate this issue :

- Using F-28, and partial payment tab to generate a "DZ" posting.

- Using F-32 to match credit memo of customer retention (posting key 19) with part of several customer retention items on different invoices (posting keys 09)

In both case, we are receiving the following error message :

Posting key 17 does not permit specification of a special G/L indicator

Message no. F5761

Diagnosis

Posting key '17' and special G/L indicator 'H' were transferred.

System Response

Inconsistent data cannot be prcessed.

Procedure

Remove the special G/L indicator online.

If the data comes from another application, the consistency of the data there must be guaranteed.

SAP is forcing the generation of a wrong posting key. In SAP standard, NO special g/l indicator (UMSKZ) is set from SD side, it will be done only for down payment. Special G/L Transaction Type ( UMSKS ) is not filled from VF01.

Is there any way in standard system to overcome such difficulties ?

Thank you in advance !!
