'''Summary:''' The MRO material management concept describes how features provide the foundation for handling materials are defined, requestedmaterial master data, reservedreservations, storage locations, and used goods movements in maintenance MRO workflows. It explains the relationship between material-related The central objects such as are <span style="font-family: Consolas, 'Courier New', monospace; color: #202122; background-color: #f8f9fa; border: 1px solid #c8ccd1; border-radius: 3px; padding: 1px 4px; white-space: nowrap;">Material</span>, <span style="font-family: Consolas, 'Courier New', monospace; color: #202122; background-color: #f8f9fa; border: 1px solid #c8ccd1; border-radius: 3px; padding: 1px 4px; white-space: nowrap;">Material MasterMaterialMaster</span>, and <span style="font-family: Consolas, 'Courier New', monospace; color: #202122; background-color: #f8f9fa; border: 1px solid #c8ccd1; border-radius: 3px; padding: 1px 4px; white-space: nowrap;">Reservation</span>, <span style="font-family: Consolas, 'Courier New', monospace; color: #202122; background-color: #f8f9fa; border: 1px solid #c8ccd1; border-radius: 3px; padding: 1px 4px; white-space: nowrap;">GoodsMovement</span>, and how these objects <span style="font-family: Consolas, 'Courier New', monospace; color: #202122; background-color: #f8f9fa; border: 1px solid #c8ccd1; border-radius: 3px; padding: 1px 4px; white-space: nowrap;">StorageLocation</span>. Materials are connected linked to master data and storage locations. Reservations link materials to tasks and define planned or actual quantities for maintenance work packages.
</div>
In a maintenance workflow, users may need to know:
* which material is required for a task or work package* whether which material master data belongs to a material* where the required material is availablestored* how much material is requiredavailable* how much material has is already been reserved* whether the material can be usedwhich reservations exist for a task* whether a reservation is still openplanned, confirmed, issued, fulfilledcancelled, or no longer relevantexpired
The material management concept implementation separates the general definition of a material catalogue from its the actual usage in maintenance workmaterial quantity and reservation handling.
The material management implementation is built around the following main objects:
