Among the suggested selections:

Concerning the allocation of the shipment requests associated to the contract order, if a shipment request is allocated where the calculated customer credit level is greater than the authorized credit level, the user will get a message requesting confirmation (if the user setup SCDTUNL authorizes it).
If not it will not be possible to allocate the shipment request and a blocking message will be displayed.
If the customer credit level is blocked, the delivery requests associated to the contract order cannot be allocated and new open orders for this customer cannot be created.
