FSCM- Orders in status B with worng credit exposure

Dear all,

I have a problem with one specific case. Below the complete scenario

Order type: miscellaneous (order without delivery) by VA01

Case 1: order creation, status B due to FSCM check. Unblock the order - > exposure 100 OK = 1000

Case 2: sales modification , status B again. Unblock the order -> exposure 100 KO (1000 + new one).

It's strange that when I modify again an order exceeding the exposure, the previous exposure amount is not cleaned. So, the credit exposure is the sum of the old one and the new one.

Any idea?

Thanks a lote

Elena
