The subcontracting process was simplified in SAP S/4HANA and now MRP requires the usage of MRP areas to segregate the stock provided to the subcontractor and the subcontracting demand from the plant stock and demands. SAP created transactions OMIZA and OMIZB, to segregate the creation of storage location and subcontracting MRP Areas.Transaction OMIZB can be now be used to create subcontracting MRP Areas and it is open for changes in the productive system without a request.Īssignment of subcontracting MRP Areas to the material master is not required As this number will usually not be the same in development, quality and production systems, it was necessary to open the customizing transaction OMIZ for changes in the productive system, so that the subcontractor number could be manually adjusted (a long time ago I wrote this blog explaining how to do that).Īs of S/4HANA 1909, however, it is no longer necessary to open the customizing transaction OMIZ for changes in the productive system. When creating a subcontracting MRP Area in customizing, we always need to add a reference to the subcontractor (supplier) number. New transaction to create subcontracting MRP Areas This blog explains in detail how to activate the Intra-Plant View in SAP S/4HANA 1809 or subsequent releases. The new intra-plant view, delivered in SAP S/4HANA 1809 changed the system behavior and introduced a new tab in the Stock/Requirements List, bringing back the possibility to have an overview of the planning situation across multiple subcontractors and storage locations. This blog provides a summary of all the improvements delivered for MRP Areas in SAP S/4HANA, across multiple releases.īefore the migration to SAP S/4HANA, planners could find an overview of the planning situation in different subcontractors and storage locations planned separately in a single screen of the Stock/Requirements List (transaction MD04). In the first SAP S/4HANA releases, however, this was no longer possible with MRP Areas, as the planned would have to access each MRP Area separately. However, not everyone knows that SAP provided many new features that helped companies to effectively use and manage MRP Areas in SAP S/4HANA.
If you are familiar with the simplifications implemented in MRP processes in SAP S/4HANA, you should be aware that the usage of MRP Areas is now mandatory for storage location planning and it is also recommended for subcontracting planning in MRP (if you are not aware of these simplifications, I suggest you to take a look into this blog).
