Allocating BOM Items using BOM Transfer 
Purpose
If you use bill of material (BOM) transfer to allocate BOM items to a network activity, subsequent changes in the BOM are automatically updated in the network.
You can only allocate reference points for items in a bill of material, not for the component in the header. You can only allocate such components as
Assembly ItemsYou cannot allocate BOM items to a standard network using reference points. You can however enter reference points in the data fields which have been defined for this purpose, so that when you use this standard network to create an operative network the system also copies the reference points.
During allocation using reference points, the system ignores material components that you have already manually allocated to a network activity. These material components do not appear in the list of allocations.
Prerequisites
To use BOM transfer, one of the following prerequisites must be met for the activities or the network.
Process Flow
In general you only do this once, the first time you want to use BOM transfer. Hereafter you should not need to change the designation of the data fields again.
The reference point in the BOM item must be the same as the reference point in the network activity, to which you want to allocate the BOM item. Generic entries are allowed.
Result
The BOM items and the activities are linked logically.
For information about how changes to BOMs affect the network, if you execute the allocation again, see
The Effects of Changes in Bills of Material and BOM Transfer.
