SAP Credit Check

Hi

I got a question regarding the critical fields check in SAP credit management.

Does changing of payment terms (a critical field) checks whether the it is within the credit horizon?

In system we have set a credit horizon of 7 days. But delivery is to be made next month (so it is more than 7 days). When i change the payment terms, system does not go through the credit check and order is not blocked.

Is this how standard SAP is suppose to react? This is for ECC6.0. Previously was on 4.6C

Thank you.
