Receiving Report. As noted previously,a copy of the purchase order goes to the receiving clerk to give advance notice in preparation for the for the arrival of the materials ordered. This is done to facilitate planning and to provide space for the incoming materials. The receiving clerk works in the receiving department where all incoming materials are received, opened,counted or weighed, and tested for conformity with the order . If the materials received are of too technical a nature to be tested by the receiving clerk, an engineer from the production manager's office may perform the inspection, or the materials may be sent to the plant laboratory for testing.
