Dunning a customer ...
I'd like to know if, dunning a customer (t.code F150), SAP locks the creation of new sales orders (t.code VA01) for that customer (SD).
If my understanding is not wrong, dunning willnot block the creation of new sales orders for the customers.
Creation of the sales orders is blocked only if the credit of the customer is not within the required limits.
Dunning is the procedure carried out by the companies to get the outstanding payments due from the customer. Like they send the reminder letters or legal action.
Unless otherwise specified or any customized code written, dunning will not block the order creation for the particular customer.
