Infor LX & BPCS Tip: MPS Planned vs. MRP Planned

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 LX (ERP LX) will calculate the 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.

Tips:  LX | BPCS | M3

Previously, Material Requirements Planning (MRP) preferred practices meant that the component's due date was the same as the parent's shop order release date. Because MRP trends have changed, the preference for this due date is the day before the release date of the parent. Although Infor LX already has this functionality in Shop Order Maintenance programs (SFC500), users could not change how due dates were determined for lower-level shop orders in Multi-Level Shop Order Release, SFC530D.

This enhancement provides an additional parameter for Multi-Level Shop Order Release. This parameter allows the user to change how the due date of the child components is determined. The Multi-Level Shop Order Release, SFC5302, has a new parameter for shop orders. The Due Date of Children = Release Date of Prent (Due Date of Children) field allows the user to set the due date determined for multi-level shop orders.

This feature uses different exchange rates in the user's inventory processes by using new macros in Post Inventory to G/L, INV920D. INV920 used macros limited by the Override Exchange Rate parameter set on the book in Book Definition, CEA105D3. If the Override Exchange rate parameter is set to No, the macro uses the Rate Type of the Book. If the Override Exchange parameter is set to Yes, the macro uses the Rate Type of the Order Company. This enhancement provides macros that use the Rate Type of the Order Company. This enhancement provides macros that use the Rate Type of the Warehouse Company, Order Company, or the Book regardless of the Override Exchange Rate parameter in the Book.

Tips: LN | Baan

Instead of sharing tables through logical linking, you can replicate table content between companies. This approach allows certain non-key attributes of a record to vary by company. For example, if you replicate bills of materials rather than sharing them, each company can associate a different warehouse with the same bill of material. This way, the bills of materials are consistent across companies, while the warehouses can differ.

Replication also enables selective availability of records in other companies. For instance, when replicating items, you might limit which items are available in a sales company based on their item group, only including end items. You can further refine replication to specific subsets, such as particular item groups.

Keep in mind that replication requires any referenced tables to be either replicated or shared as well.
