[SD] User Exits For Credit Checks And Risk Management
If you want to carry out your own individual credit checks, that differ from those in the standard system, you must define them in the following user exits:
User exit for availability check
User exit USEREXIT_AVAIL_CHECK_CREDIT exists in Include MV45AFZF.
This user exit allows you to determine whether the system should or should not carry out an availability check after a blocked document has been released or after a new credit check.
Risk Management for Receivables
Using this user exit, you can define new forms of payment guarantee.
