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

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, your ERP will calculate the cumulative lead time (also called “the Critical Path”) for you.


Infor LN does not differentiate between the two. It is simply Enterprise Planning EP with one set of planned orders. It's possible to set up items and generate orders at plan levels, but not necessary. In theory, you could make plan level 1 similar to MPS items.

Another way of defining independent demand in LN terms is that it is demand not related to other planned items. Dependent demand comes from related planned items above in the BOM structure.

COLT still exists in the purchase and manufactured planned items. It has non-critical and critical lead time based on components set as critical. Once calculated it can be used to update the order and planning horizons of a plan item.

Tips:  LX | BPCS | M3

Role-Based Security introduces Role type profiles and allows combining the use of Role profiles with the traditional LX User type security profile functionality. The new Role type profile can be defined to allow or deny access to All Products, Attention Key, Products, Programs, and Transaction Effects. Facility, Warehouse, and Company securities are still defined solely by the User profile settings and are not affected by the assignment of a Role. Where applicable, the Role authority is displayed alongside the User authority on the security profile maintenance screens making it easy to see where there are differences in authority between the User and the assigned Roles. 

When Users are assigned to Roles, security access in LX becomes a combination of authorities granted or denied by the Role, plus any User Exceptions. User Exceptions override authorities set by the Roles. A User can also be assigned to more than one Role.

Tips: LN | Baan

You can define internal trade relationships between enterprise units or individual warehouses of the same logistic company for the transfer of material, labor, or other costs between warehouses, and to generate invoices for these without using sales orders and purchase orders. For example, you can use this to transfer goods between warehouses in different countries.


You can define warehouse surcharges, which are added to the actual costs of the goods either when the goods are issued from a warehouse or when the goods are received.

In Baan IV, requirements for an MPS item with the order method lot-for-lot result in daily planned MPS orders.

For example, if a plan period contains 10 working days and the net requirements for an item in that period is 2000 pieces, an MPS planning run generates one planned MPS order of 200 pieces for each working day in the plan period.

In Infor LN, requirements for a planned item with the order method lot-for-lot result in one planned order per plan period.

For example, if a plan period contains 10 working days and the net requirements for an item in that period is 2000 pieces, a master planning run will generate a single planned order of 2000 pieces for the first working day in that plan period. To influence the order quantity of the planned orders, enter appropriate values in the Maximum Order Quantity field and the Order Interval field in the Items – Ordering (tcibd2500m000) session or choose a fixed order quantity.
