Exercise No. 27: Purchasing Process
Transfer the following verbal description into an ERM
a) Suppliers (Supp-#) are assigned to purchase organisations (P-Org). The information record determines from which of these combinations a material (Mat-#) may be purchased from.
b) Purchase requisition lists (PRQ-List) contain line items; each line item refers to a material. There are allocations as to which information record is applicable for the handling of the particular line item.
c) Eventually, these allocations are uniquely assigned to purchase orders (PO-#); however, purchase orders can be collective orders. Each purchase order refers to exactly one supplier.
