At the time of sale order creation, just before saving the sale order want to check the Customer credit limit.
It should include the current order value also and populate an informational message
' % credit limit has veen used'.
Searched SDN and found the user exit 'LVKMPFZ1' subroutine 'USER_CREDIT_CHECK1'. Tables KNKK stores the credit limit value but how to calculate the limit used inclusive current value.
The main concern is the message comes as we enter sold to party and press enter. It should come when we enter the quantity in the order so that it can calculate the current order value also.
