Credit Check while doing Sales Order Entry

Hi All, a quick one please. If I have a customer with credit limit defined, what extra setups are required (and the process flow) to make sure that I get an error while doing Sales Order Entry if Order Amount goes beyond Customer Credit Limit? Thank you.

So long as you turn on processing option #1. Customer Credit Check (tab Order Holds) is on it always goes through CreditCheckProcessing.

In case your credit checking level is P or L then you may check whether you have specified credit limit amount children (if so, set credit limit amount zero for children).

Plus, easier way you can check is through P42050 which will give you actual amount sitting on from F03012, which is to hold so long as [(as is F03012.APRC) + (F4201.OTOT)] > F03012.ACL.
