If you want to use dunning areas but only one dunning procedure, specify the dunning procedure in the business partner master record. You do not have to make a breakdown by dunning area in the master record. The system determines the correct dunning procedure automatically from the dunning area entered in the line items. In effect, you use only one dunning procedure; the information concerning the dunning area is stored automatically in the master record per dunning area, and you can dun separately per dunning area.

Define the dunning area and enter it in the business partner master record.
