BOM Explosion with Phantom Assemblies 

Use

The phantom assembly represents a logical grouping of materials. These materials are grouped together from the construction point of view and are all maintained together. From the production point of view, however, these materials are normally not assembled. The phantom assembly is also used as an entry aid.

Prerequisites

You have entered a special procurement key for Phantom assembly in the Special procurement field in the material master (MRP 1 view) for the assembly.

You define special procurement keys in Customizing for MRP in the IMG activity Define special procurement type.

You can combine the Phantom assembly attribute in Customizing with every possible special procurement type. Example: A material, on the one hand, is sold as a spare part from stock to customers and is procured using stock transfer as the special procurement type. The same material, on the other hand, also appears in several BOMs, but is treated as a phantom assembly there.

Features

If a BOM item is a phantom assembly, the dependent requirements of the higher-level assembly are directly passed on to the components of the phantom assembly. The phantom assembly itself is still not taken into account.

If it is necessary, in individual cases, to create dependent requirements and procurement proposals for the phantom assembly during the planning of a material, you can override the Phantom assembly attribute in the BOM. Enter an appropriate indicator for the explosion type in the item screen of the BOM. You maintain the explosion type in Customizing for MRP in the IMG activity Item data ® Define explosion types.
