Infor LN & Baan OPERATIONS Tip: MPS Planned vs. MRP Planned

When deciding what items should be MPS (Master Production Schedule) planned and what items should be MRP (Material Requirements Planning) planned, it's crucial to understand the nature of the items and their demand sources. Here's a breakdown:

  • Master Scheduled Items:

    • Master Scheduled Items are typically finished goods or service items.
    • These items receive their requirements from both Independent and Dependent demand sources.
       

  • Independent Demand:

    • Independent demand cannot be calculated from higher-level demand in the product structure.
    • It is driven by forecasts or actual customer orders, primarily applicable to Finished Goods or Service parts sold to customers.
       

  • Dependent Demand:

    • Dependent demand is derived from higher-level demand in the product structure.
    • It includes components, raw materials, and sub-assemblies.
    • Dependent demand items are not typically part of Master Production Scheduling (MPS).
       

  • Service Parts:

    • Service parts can have both independent demand from forecasts or customer orders and dependent demand from higher-level demand if they are used in sub-assemblies or other products.
       

  • Cumulative Lead Time:

    • Cumulative Lead Time is a concept used in MPS.
    • It combines the fixed lead time and variable lead time required to produce a product.
    • It represents the longest path through a Bill-of-Materials (BOM).
    • Your ERP system will calculate the cumulative lead time (Critical Path) based on MPS setup options.
       

  • Infor LN Approach:

    • Infor LN does not differentiate between MPS and MRP planning.
    • It uses Enterprise Planning (EP) with one set of planned orders.
    • While you can set up items and generate orders at plan levels, it's not always necessary.
    • In theory, you could treat plan level 1 similar to MPS items.
       

  • Defining Independent Demand in LN:

    • In LN terms, independent demand is demand not related to other planned items.
    • Dependent demand comes from related planned items higher up in the BOM structure.
       

  • COLT (Cumulative Order Lead Time):

    • COLT exists in the purchase and manufactured planned items.
    • It considers non-critical and critical lead times based on components marked as critical.
    • Once calculated, COLT can be used to update the order and planning horizons of a planned item.

Relevant Sessions:

In Baan IV:

  • Maintain Item Data (tiitm0101m000)
  • Generate MPS (timps3201m000)
  • Maintain Master Production Schedule (timps3101m000)
  • Display Planned Inventory Movements by Item (timrp1510m000)
  • Display Planned MRP Purchase Orders (timrp1521m000)

In Baan V:

  • Plan Item Data (cprpd1500m000)
  • Item Master Plan (cprmp2101m000)
  • Time-Phased Overview (cprrp0520m000)

In Infor LN:

  • Item – Planning (cprpd1100m000)
  • Item Master Plan (cprmp2101m000) - Same as Master MPS if used

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

In Baan IV, inventory valuation is done by standard costs, unless you use projects. If you use projects, it is based on estimated or actual costs.

In Baan V and LN, you have the choice of LIFO, FIFO and MAUC (Moving Average).

Sales Order Acknowledgements in Baan IV:
After a sales order is entered in Baan IV, users can print an order acknowledgement in Print Sales Order Acknowledgements/RMAs (tdsls4401m000), after which it can be sent to the customer.

Sales order acknowledgements in ERP LN:
In Infor LN, users can still use the Print Sales Order Acknowledgements/RMAs (tdsls4401m000) session to print order acknowledgements, however, the following functionality is added to this session:

  • In the Documents to Print field users can select whether to print order acknowledgments and/or return material authorizations.
  • With the Promotions check box users can indicate whether to print promotions on the order acknowledgement, if promotions apply to the order.
  • Users can control the printing of order acknowledgements based on the order amount and/or the delivery date.

These conditions only apply for order types that do not have the Print Sales Order Acknowledgements/RMAs (tdsls4401m000) linked as a mandatory activity to the order type in the Sales Order Type - Activities (tdsls0560m000) session.
