Planning at Phantom Assembly Level (59)
Purpose
This strategy can be used for a set of components that have the following features:
Prerequisites
You must maintain the master data of the phantom assembly as follows:
You also must set the Backflush field to 1 (2 may also be possible) on the MRP screen of the material masters for the components of the phantom assembly.
Backflushing is essential because the components are planned with only one planned independent requirement which can only be planned correctly if all reservations are reduced at the same time. This is only possible when the goods issue for the components is posted at a later stage as in backflushing. In addition, all components of the phantom structure have to be linked to the same operation.
BOMs must be maintained for the finished products and for the phantom assembly.
Process Flow

For a detailed example of the entire process, see
Sample Scenario: Strategy 59.This strategy should be used in the following business context:
In contrast to strategy 70, however, stock does not exist for the assembly in strategy 59, due to its ‘phantom’ nature.
