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

Determining whether to use Master Production Schedule (MPS) planning or Material Requirements Planning (MRP) planning for items in Infor LX and BPCS involves understanding the nature of the items and their demand characteristics.

Master Scheduled Items typically encompass finished goods or service items. These items receive their requirements either from Independent demand, Dependent demand, or a combination of both.

  • Independent Demand: This refers to demand that originates from sources such as forecasts or actual customer orders. Items sold directly to customers fall under this category.
  • Dependent Demand: Derived from higher-level demand within the product structure, dependent demand comprises components, raw materials, and sub-assemblies. These items are not typically designated as Master Scheduled Items.
  • Service Parts may exhibit both independent demand, originating from forecasts or customer orders, and dependent demand, stemming from their use in other sub-assemblies or products.
  • A crucial concept in MPS is the Cumulative Lead Time, which combines fixed and variable lead times required to produce a product. It represents the longest path through a given Bill-of-Materials (BOM). In Infor LX (ERP LX), the system calculates the cumulative lead time, also known as the Critical Path, based on setup options. Utilize the "indented BOM" display in BOM300 to identify the item with the longest lead time. Additionally, you may need to use Action 21, Line Detail, to view the lead time ("L/T") for each item.

You can change your master schedule by specifying the type of master schedule update to perform. You can run a Net Change or Regenerative Schedule.

You also have the ability to clear the lower level requirements out of the Planned and Firm-Planned Order file.

Understanding: What Was Issued to the Shop Order

The shop order inquiry program provides several function keys. By using the function key for the material, the display will present what components have been issued under the issued quantity column. You are also presented with the required quantity. While viewing the quantities you may see that more was issued than what was required. Possibly there was scrap and more material was required to be issued. Perhaps there was an over issue and the balance of the material is slated to be returned to stock.

A red flag should go up if the Shop Order quantity finished is equal to the required quantity for the end item and all the components have not been issued. You may want to investigate why.

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.
