Purchase/Manufacture Codes
Purchase/manufacture (Pur/Mfg) codes are used throughout the system to identify how items are typically obtained; for example, items you ordinarily purchase from another company typically have a code of P, and those you manufacture yourself may have a code of M. Specify purchase/manufacture codes for items in one of the following programs:
• Item Master Maintenance (1.4.1)
• Item Planning Maintenance (1.4.7)
• Item-Site Planning Maintenance (1.4.17)
Two purchase/manufacture codes have special significance in flow scheduling:
• W (Flow manufactured). When you add an item to a production line in Production Line Item Maintenance (17.21.1.7) with a purchase/manufacture code other than W, the system displays a warning message.
Additionally, when you add MRP-planned orders to flow schedules using Import MRP Orders to Schedule (17.21.9), you can optionally limit the selection to items with a W purchase/manufacture code.
• L (Line manufactured). When you export a flow scheduled order to a Repetitive or Advanced Repetitive production line using Export Schedule to Repetitive (17.21.10), you can optionally limit the selection to items with this code. They are normally manufactured on a repetitive line.
Additionally, when you import an MRP-planned order for one of these items to a flow schedule, the system updates the associated work order to change it to type W. This means the flow schedule can be selected for export to a repetitive production schedule.
