Material Requirements Planning Areas (SAP Library - SAP Advanced Planner and Optimizer (SAP APO))

Material Requirements Planning Areas

Use

In this section you will find information about how Material Requirements Planning Areas (MRP areas) are transferred from SAP R/3 to the location master data of the SAP Advanced Planner and Optimizer (SAP APO).

An MRP area is understood to be a planning area within a plant that is subject to separate inventory management and material requirements planning.

Features

The Material Requirements Planning Area in SAP R/3

You can find information on the MRP areas in SAP R/3 under the components Logistics ® Production Planning and Control (PP) ® Requirements Planning ® Special Planning Process ® MRP Area.

The Material Requirements Planning Area in SAP APO.

The SAP R/3 MRP area of a plant is represented as the location Production Plant in SAP APO. All additional SAP R/3 MRP areas are represented as locations with their own location types.

Restrictions:

The SAP R/3 MRP area may only be assigned to one storage location.

The process Subcontracting MRP Area in SAP R/3 is supported in APO without an MRP area.

Integration R/3 – APO

You can transfer the MRP area to SAP APO via the integration model APO Core Interface (CIF) and then create this as a location with the corresponding location type in connection with the MRP area of a plant or another MRP area.

If MRP area processing is activated in SAP R/3 you can use CIF to control whether you would like to work with MRP areas in SAP APO.

SNP Planning

In SAP APO you can plan stock transfers between MRP areas. For this, transportation lanes need to be manually created in SAP APO. After an SNP planning run the system converts the stock transfer requisitions generated in SAP APO for the MRP area into SAP R/3 stock transfer reservations that can be integrated into SAP R/3. In SAP R/3 you can carry out the stock transfers with the transactions intended for this in inventory management. If production is also being planned and this contains PPM components, then component planning is only possible if the components are also in the MRP area of the plant.

For the ATP check in SAP APO you must create rules (location substitution) in order to be able to carry out cross-MRP checks.

PP/DS Planning

PP/DS planning with MRP areas is currently only possible in a restricted form.

You can only transfer resources and PPMs to the production location using CIF.
You have to create PP/DS planned order components that are to be planned in a different MRP area to the PP/DS planned order by using stock transfers in APO. This is different to the R/3 features.

In principle, it is possible to use MRP areas if you are planning the planned order and all associated components in the same MRP area.
