How to Handle a Card that is both a Customer and Supplier and you are Issued with a Supplier Credit

If a CardId is flagged as both a Customer and a Supplier and you are issued with a Supplier Credit instead of the full amount owing on the Customers Card.

1. On the customers card you would have a open item that is outstanding.
2. The customer that is also flagged as a supplier has part paid you for this open item. However they issue a Supplier Stock Credit for the Balance owing on the customer card. No Stock was returned and no money exchanged.
3. Enter firstly a transaction against the card to stand for the Stock Credit. This would be a Misc SUPCRE as the goods were not returned to the supplier. Dissect this transaction against a GL account of Supplier Discount Received (or create a contra account).
4. Now you have to account for the STKCRD that should have a value that lines up to the balance owing on the customers card. Enter a CUSCRE and dissect this against Supplier Rebate Received as no physically money was received. 
5. Alloocate the CUSCRE against the balance owing on the customers card open items.
6. The General ledger affect will be a nett result of Zero to Supplier Rebate received.
