Assembly Processing w/ Char. Planning (89)

Purpose

This strategy creates automatically planned independent requirements for the component of a configurable material. This works as described in strategy 70. The big advantage is that you don’t have to enter the component’s quantities manually any more. They are calculated based on the quantities of the planned independent requirements for the configurable material and the usage probabilities of the corresponding characteristics.

The allocation takes place at the component level, rather than at the configurable material level. As a result, MRP planning runs do not change the components’ planned requirements based on allocation at the configurable material level as seen in strategy 56.

The planned independent requirement for component may be entered manually, as described in strategy 70. However an easier and more efficient method of producing independent requirements for the component of the configurable material is through R/3’s Long Term Planning process.

Prerequisites

In addition to the usual master data settings such as creation of BOMs and routings and the various configuration data (Configuration: Classes, Characteristics, Configuration Profile, Object Dependencies) the following has to be set up. For Classes and Characterisitcs, choose Logisitcs ® Central functions ® Classification. For Configuration profiles and Object dependencies, choose Logisitcs ® Central functions ® Variant configuration.

Material Master

Item Category group; for example. 0002
Assign strategy group 89
Availability Check 01, to check with replenishment lead time

Components

Consider setting the ‘Individual/Collective’ indicator to 2.
Components must have strategy group ‘70’ (or ‘59’) in order to get dependent requirements from the planning of a configurable material.
‘Mixed Indicator’ must be set to 1.
Consumption parameters (Consumption Mode, Fwd Consumption, Bwd Consumption), are activated such that planned independent requirements can be impacted

Mark those characteristics as ‘relevant for planning’, which should have a usage probability in demand management as described in Creating PIRs for Characteristics Planning
