EXIT to check the customer Credit limit.
when i am creating the sales order for the customer if credit limit exeeds the it should give the eeror message but in my system it is giving the warning message. for this do we need to write any EXIT or do we need to do any settings.
U wud need to write and exit for that.
Try using exit MV45AFZZ which wud work mostly, and write the code for it under
Check out in SPRO-> Sales and Distribution->System Modifications->User Exits->
Check User Exits For Credit Checks And Risk Management and User Exits in Sales->User Exits In Sales Document Processing. In all exits check the documentation next to it. It will tell u in detail what can be used.
