This indicator determines the special procurement type of a material that is either procured externally or produced in-house.

The system determines the special procurement key from the Procurement type and Special procurement fields in the material master record (Detail Screen: MRP 1) and displays the value if the BOM is only assigned to one plant.

The system only displays the values that are relevant to the explosion type for a BOM item.

• Phantom assembly

A phantom assembly is only required for engineering/design. It does not occur physically in the course of production. In the planning run, the component materials of the assembly transfer requirements. The header material of the assembly is not planned.

The following graphic shows how a BOM that contains a phantom assembly (component B) is exploded for engineering/design and for production in the standard R/3 System. The engineering/design explosion includes the phantom assembly, whereas production only includes the components of the phantom assembly (components B1 and B2).

In the standard R/3 System, the special procurement key phantom assembly has the value 50.

Material components of this special procurement type are produced in an order network using a special production order.

In the standard R/3 System, the special procurement key direct production (collective order) has the value 52.
