Production in Alternative Plant (SAP Library - Material Requirements Planning (PP-MRP))

Production in Alternative Plant

Implementation Options

You can define that a particular product is to be produced in an alternative plant (that is, the production plant) from the planning plant. The planning of the product is carried out in the planning plant but it is actually produced in the production plant. The product's BOM is created in the production plant.

Prerequisites

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

You have assigned this special procurement key to the assembly in the material master of the planning plant (MRP 2 view).

You have created a material master for the material in the production plant.

Process Flow

The following graphic shows the steps involved in producing material in another plant:

You first plan material requirements in the planning plant. During the planning run, the system creates a planned order for the assembly in the planning plant, if this is necessary.

The following is to be taken into account for the scheduling of the planned orders in the planning plant:

The system uses the in-house production times and scheduling margin key entered in the material master record for the planning plant to determine the basic dates.

If MRP is carried out using lead time scheduling via the routing, the routing and scheduling margin key in the production plant are the basis of the production date calculation in.

If you have defined that the basic dates are to be adjusted for the production dates in lead time scheduling (Customizing, IMG activity Define scheduling parameters for planned orders) the system calculates the basic date by adding the production finish date and the float after production. The system uses the production start date minus float before production as the order start date. The system determines the float before production and the float after production from the scheduling margin key in the material master record for the production plant.

You plan material requirements in the production plant. The system explodes the BOM for the assembly in the production plant and determines the dependent requirements.
You convert the planned order in the planning plant into a production order.
The dependent requirements in the production plant are converted into a dependent reservation and production of the components in the production plant is initiated.
When creating the goods receipt for the production order, the stock in the planning plant is increased.
