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.

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.

The planning data for the method of manufacturing is defined in Routing. A routing consists of operations, with each operation identifying the last to be carried out in a work center and/or on a certain machine defined for a specific site.

Routings can be as follows:

  • Standard Routing - A generic routing that can be attached to multiple items
  • Item specific - A routing that is applied to one item
  • Network routing - A routing containing sequentially ordered operations and parallel operations
  • Order quantity dependent routing - A routing that is defined for a specific quantity of items

You use the Routing module to record routings for manufactured items. You can define the following:

To improve performance and reduce database growth, deleting records is highly effective. The disadvantage of deleting records is that data is no longer available. Usually, however, not all records need to be saved. For example, line activities are stored by warehouse. Normally, you do not need to keep these records. Therefore, after closing a warehouse order, line activities can be removed. The User's Guide for ERP LN Archiving and the corresponding Baan IV/V Guides describe several sessions you can use to delete old data. Other data such as items and business partners can be reviewed once in a while, after which you can delete the data you no longer need. For every order and contract table, a session is available to archive and delete old orders. In these sessions, you can specify several characteristics to select the orders to be removed, such as date or status. Run these sessions on a regular basis.
