Module Planning - Overview

Project Control relies on components with long lead-times being available on time. When the sales order demand is not yet entered, or when the bill of material (BOM) for the customized product structure is not ready, Enterprise Planning cannot properly plan these critical materials.

To compensate for this, a fixed planning quantity for the components can be specified in the Module Planning (tipcs4120m000) session. When generating an order planning, Enterprise Planning will create planned supply for these components.

When the actual sales order is entered or engineering on the BOM is completed and there is still a fixed plan quantity on the module, the generated order planning orders too much supply. A signal is raised for the user to clear the Fixed Plan Quantity check box on the module so the module planning is no longer taken in to account.

The module demand is handled differently from regular demand, like sales order demand.

  • The module demand creates a planned supply order (a planned production order or planned purchase order).
  • The date on this firm planned supply order is the earliest finishing date of the linked activity.
  • The module demand does not consume the on-hand inventory, or the planned supply of the customized item.
  • The on-hand inventory or planned supply of the customized item's derived-from item is not get consumed by the module demand.
  • The module demand does not lead to planned supply for safety stock.
  • When the planned supply for the module demand is transferred to Job Shop Control or Purchase Control, the Fixed Plan Quantity in Project Control is automatically lowered by the transferred quantity.
Note: 
  • Lot sizing applies to the firm planned orders.
  • The firm planned orders are not removed by re-planning, even in case of over-supply.
  • The Module number is visible in the Planned Order (cprrp1600m000) session header.

When multiple module demands exist for the same planned item, supply for all demands is combined in to one firm planned supply order, unless order intervals are defined in the item ordering data.

When both module demand and regular demand exist for an item, Generate Order Planning (cprrp1210m000) performs these steps:

  1. The module demand is planned, creating the firm planned supply for the module demand, on the date determined by the related activity.
  2. The regular demand is planned. The firm planned supply is then consumed by the regular demand.
Note: 
  • The date of the firm planned order is not changed.
  • An exception message can be logged to indicate that the firm planned supply is late or early.
  • If the regular demand is not completely filled by the firm planned order, new planned supply will be created for the remaining quantity, for the requirement date of the regular demand.
  • The module demand is not shown in the Item Order Plan (cprrp0520m000) session, because its supply can be consumed by other demand.

Example

The Item Order Plan (cprrp0520m000) shows that an item has a module demand for 4 pieces of material on 24 December 2013, and a sales order of 6 pieces on 25 February 2013.

This results first in a firm planned production order on 24 December 2013 for the module demand. It also fulfills part of the sales order, creating the exception message ("Demand will be delivered late.").

For the remaining 2 pieces of the sales order, a planned distribution order is created to consume the on-hand inventory of the derived-from item.
