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 “Use Customer Requested Delivery Date” parameter has been introduced in the Sales Order Parameter (tdsls0100s400) session, which is used to track the customer’s requested delivery date.

If this parameter check box is selected, various additional date fields become available to track the customer Initial Requested Delivery Date and the Original Promised Planned Delivery Date.

In a scenario where performing job A depends on the result of job B, it is hard to decide at what time job A must be scheduled, and how long job B runs. To handle dependent jobs, you can now create a job group. Use the Job Groups (ttaad5140m000) session to create a job group. A job group has a name, with the same characteristics as a job name, and a description. The Status and User of the job group are handled automatically.

After creating the job group, the jobs are added to the group, approximately in the order the jobs must be performed. The first job in the group (with the lowest Group Number) determines the handling of the whole job group, such as execution date and whether the job group is being repeated. If the job group is not repeating, the job group and all non-repeating jobs in the job group are deleted when the job group has run.

The dependencies of the jobs in the job group are also determined. A job in the job group can only depend on a job in the same job group with a lower job number.

You can use the specific options in the Job Groups (ttaad5140m000 andttams5640m000) sessions to change the status of the job group. The job group statuses have the same meaning as the status of the jobs and the same status changes are allowed.

Note: Job groups are only handled by the BSE service Job Scheduler Service.
