Infor LX & BPCS Tip of the Week: MPS vs. MRP

What items should be MPS planned, and what items should be MRP planned…

Master Scheduled Items are those items that are finished goods, or service items, that receive their requirements either specifically from Independent demand, or both Dependent and Independent demand.

  • Independent Demand is demand that cannot be calculated from higher level demand in the product structure, and therefore must be either a forecast or an actual customer order (Finished Goods or Service parts sold to customers).
  • Dependent demand is derived from higher level demand in the product structure. Dependent demand includes components, raw materials, and sub-assemblies. (these are not normally Master Scheduled Items).
  • Service Parts may have both independent demand from forecast and/or customer orders, as well as dependent demand from higher level demand if that item is also used in other sub-assemblies or products.
  • Cumulative Lead Time is a concept used in Master Production Scheduling (MPS) that combines the “fixed” lead time, and the “variable” lead time needed to produce the product. It is the longest path through a given Bill-of-material. Based on the MPS setup options, Infor/ERP LX will calculate cumulative lead time (also called “the Critical Path”) for you (use the “indented BOM” display in BOM300 and find the item with the longest lead time “L/T”). Note: You may have to use Action 21, Line Detail, to see the “L/T” lead time for each item.

Understanding: The Cycle Count Alternative

The best way to cycle count is to count the same number of items each day and at the same time each day. The goal is to count your “A” items 4 times a year. The “A” items should be those item that are about 80% of the total inventory value and 20% of the total items. Consider creating your own cycle count schedule then instead of using the cycle count transaction, use the inventory adjustment transaction. The item balance is changed at the time the transaction is keyed. The transaction list can be used for the reconciliation process.

Understanding: The Cycle Count Transaction

If you rely on BPCS to provide you with a cycle count list, the number of items could vary from day to day from a few items to count, to several. So the person doing the cycle counting may spend a few minutes to a few hours counting items. After the cycle count is complete, the balances are not changed until the reconciliation is complete. This process could take some time before the balances are changed.

The cycle count transaction process is similar to the physical inventory transaction process.
