Multiple credit memo creation for single credit memo request

Question

Hello,
The problem is that I am able to repeatedly create multiple credit memos for the same credit memo request.  The system is not stopping me by saying "This order is fully invoiced".
I observed the following in the customizing:
1. If the sales document category of the billing document (in VOFA transaction) is 6 (Intercompany credit memo), then I am able to create mulitiple credit memos against the same credit memo request.
2.  When I change the sales document category of the billing document to O (credit memo), then the system stops me from creating multiple credit memos against the same credit memo request.
If I want to maintain 6 (intercompany credit memo) in VOFA and still want the system to stop me from creating multiple credit memos for the same credit memo request, then is there is any other customizing to achieve this?
Thanks,
Shankar

Shankar, most likely the billing status of your sales document is not updated. We have experienced the same (or similar?) issue with the intercompany documents and SAP refused to correct it. Here is a fragment of my message exchange with the SAP support:
We have already read the notes 63459 and 308989. They both do not apply
to our business process. The document flow mentioned in the notes is as
follows:
Sales order - customer billing document - intercompany billing document
Our document flow is different:
Contract - customer billing document - Intercompany sales order (could
be more than one order per customer billing document) - intercompany
billing document
The order-related billing status is not being updated on the
Intercompany sales order.
The process described in the notes implies one-to-one relationship
between the customer and inter-company billing documents and the sale
from a Plant that is assigned to another company. We are in the service
industry and sometimes the sale revenue has to be shared by 2-4
companies within our enterprise.
Good day. It is a standard system behaviour that if the billing document type has SD document cateogry '5' (field TVFK-VBTYP in transaction
VOFA). So it is an intercompany billing.
The order-related billing status VBUP-FKSAA is not affected by the
intercompany billing.
So its billing status remains opened, and can be billed more times.
This doesn't seem right to me. Maybe if more customers complain, they will do something about it.
To some extent this may be managed with copy requirements (VOFM), where you can prevent copying the credit memo line items that have been invoiced. However, this might still lead to the blank documents with 0 value, statuses won't be correct and in VF04 you would see the documents as not invoiced.
I had to do a core modification to resolve this issue in our system. In LV45P011 include I did the following:
* Faktura
*{   REPLACE        DC6K903001                                        1
*\  IF vbfa-vbtyp_n CA vbtyp_fakt AND vbfa-vbtyp_n NA vbtyp_fkiv.
  IF vbfa-vbtyp_n CA vbtyp_fakt.
*}   REPLACE
Hope this helps.
