Hi, Our biggest client has implemented SAP and need stock codes from us; to be loaded on the systems before they can release the purchase orders. The problem that we are facing with the stock code is that everything is unique. We are in manufacturing, each part of each assembly is unique, i.e each part has different diameters and lengths, making up an unique assembly. Any suggestion on we can resolve this? We do have a item code (complete assembly), but that is issued on receipt of purchase order. It comprises of the job number (incremented by 1 from previous job) + drawing number (incremented by 1 from previous drawing) .
