Withdrawal from Alternative Plant (SAP Library - Material Requirements Planning (PP-MRP))

Withdrawal from Alternative Plant

Implementation Options

You can specify for an assembly that the components required to build the assembly are to be withdrawn from a different plant from the planning plant (that is, the issuing plant). Dependent requirements for these components are directly created in the issuing plant. You can use withdrawal from alternative plant for both components produced in-house and procured externally. A special procurement key is defined for both procedures.

This procedure provides an alternative to using stock transport orders and is especially useful when plants are close together.

Prerequisites

In Customizing for MRP, in the IMG activity Define special procurement type, you have maintained a special procurement key for Withdrawal from alternative plant and you have entered the issuing plant there.

You have assigned the component, which is to be withdrawn from an alternative plant, to this special procurement key in the material master of the planning plant (MRP 2 view).

In the withdrawal plant, you have created a material master for the component to be withdrawn.

Process Flow

The following example shows the steps involved in withdrawing material from another plant:

An assembly in plant 0001 contains two components. Component 2 in plant 0001 has the special procurement key Withdrawal from alternative plant with the issuing plant 0002. This defines that this component is to be withdrawn from plant 0002. Therefore, when producing the assembly in plant 0001, component 2 is withdrawn from the plant 0002 but the other components are withdrawn from plant 0001.

You carry out the planning run in the planning plant, that is, in plant 0001. During the planning run, the system creates a planned order for the assembly in plant 0001, if this is necessary.
The system creates a dependent requirement for component 2 in plant 0001. A dependent requirement is created in the issuing plant, that is, in plant 0002, for the component 2 with the special procurement Withdrawal from alternative plant.
When the planned order for the assembly is converted into a production order, the dependent requirements of the components are automatically converted into dependent reservations. The withdrawal for the production order is carried out in plant 0001 for the component 1 and in plant 0002 for component 2.
