Item Planning Data
The next few pages review some of the key planning-related settings that the QMI planner has set up in Item Planning Maintenance (1.4.7) for the medical ultrasound units and its components.
Since item 01010 is the end item subject to independent demand, it is master scheduled and the planner wants the system to plan orders. Both Mstr Sched and Plan Orders are enabled (checked). This means that this item will be master scheduled (forecasted in our example), and planned orders created by MRP.
Note: MRP processes requirements the same whether the Mstr Sched box is checked or not. However, most reports and inquires in the system can be selected for master scheduled items only. This is very useful for master schedulers since they can select only their items for review.
The Order Policy of POQ (Period Order Quantity) instructs MRP to calculate demand for this item over the number of calendar days specified as the Order Period (in the example, 7) and creates one order to satisfy this demand.
Item 01010 is a manufactured item, as indicated by an M in the Purchase/Manufacture field. It has a manufacturing lead time of 1 day, shown in the Mfg LT field. The lead time is based on the order quantity of 5. Because it is a manufactured item, the system displays the setup and run times for reference. Since 01010 is manufactured, no purchasing lead time is specified.
Item Planning Data: Item 50001
Item 60005, the battery, is a purchased component required to assemble item 01010.
The Purchase/Manufacture field in this case is set to P. Most purchased component also have purchase lead times. Based on the planning information, the planner has indicated to MRP that these materials should be ordered in quantities to cover demand during an order period of 7 days, and that a purchase order for the component item should be released 3 days before the item is needed (Pur LT). Purchased items do not have setup or run time.
The field to note here is Order Multiple. Some purchased items must be ordered in multiples. In this case, the vendor has told us to purchase in multiples of 5.
Discussion
Based on this overview and the discussion of forecast consumption, do you see that QMI may have an upcoming problem meeting demand? It currently takes 5 working days to make 25 units. How can QMI address the issue of increasing capacity?
Note: For more detailed information on planning data and MRP, refer the courses on MRP and CRP and on Master Scheduling and RCCP.
Item Planning Data: Item 02003
In this example, the planning data for the Standard Connector (item 02003) has been set to normally buy enough for 10 units: Order quantity 10, minimum order of 10, and a multiple of 2. Note the purchasing lead time of 3 days.
