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.

Tips:  LX | BPCS | M3

Establishing the Quantity On-Hand and the Quantity Available.

LX maintains buckets for information associated with the following inventory transactions for each item:

  • Opening Balance
  • Issues
  • Receipts
  • Adjustments
  • Allocations for the Customer
  • Allocations for Manufacturing


The on hand quantity does not include any allocations. To arrive at the on hand quantity, start with the opening balance, less any issues, plus any receipts, then add or subtract any adjustments. Available inventory is the on-hand less any allocations.

 

 

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.

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.
