You can plan the materials required to execute a task for each operation in the maintenance order. The materials can be Bills of Materials (BOMs) components for the reference object or freely assigned materials.
Material planning in Plant Maintenance is integrated with Material Requirements Planning (MRP) and Purchasing.

Material Procurement - Internal
- Assign component in order operation.
Stock material which is kept on stock in one of your warehouses can be entered into the component view of the order operation using item category L.
- Material Reservation.
Planning a stock material with item category L leads to a material reservation.
- Order Release.
An automatic availability check is performed when the order is released. If there is no availability, the order can still be released.
- Print.
A material provision list and material withdrawal slips can be printed together with the order papers.
- Goods Issue.
The goods issue is entered with reference to the reservation number and will appear in the document flow of the order. The stock is reduced accordingly and documents are posted for the relevant accounts in FI and CO.
Material Procurement - Internal (EWM)
- Assign component in order operation.
Stock material which is kept on stock in one of your EWM warehouses can be entered into the component view of the order operation using item category L.
- Material Reservation with Recipient Location.
Planning a stock material with item category L leads to a material reservation containing a Recipient Location. The Recipient Location is used to derive the staging area in EWM and can be created via transaction IRL01. In addition, it can be set as default value for each user (via transaction EAM_USER).
- Outbound Delivery.
On posting a goods movement a logistics outbound delivery document is created in the SAP S/4HANA system.
- Outbound Delivery EWM.
On creating a logistics outbound delivery document in the SAP S/4HANA system an Outbound Delivery Order is created in EWM.
- Pick / Pack / Load EWM.
The necessary warehouse tasks are completed within EWM.
- Goods Issue EWM for Recipient Location.
The material is delivered to the specified recipient location.
The component line in the maintenance order is not editable until the delivery is completed.
Actions such as deleting a component, deleting an associated operation or rescheduling the Start and End date are not permitted on the order having an open delivery document associated with a stock component and appropriate error messages are issued in each case.
Delivery documents created using MIGO or MB26 transactions are not reflected in the document flow of the maintenance order. If for any reason the posting of goods issue or delivery document posting fails, the user has to resolve these errors using transaction COGI.
Material Procurement - External
- Assign component in order operation.
Non-stock material can be entered into the component view of the order operation using item category N.
- Purchase Requisition.
Depending on the order type, a purchase requisition is generated either when the order is saved or when it is released.
- Order Release.
Latest point in time when purchase requisition can be created. A standard purchaser receives the purchase requisition.
- Purchase Order.
In purchasing a purchase order is created with reference to the maintenance order.
- Goods Receipt.
A goods receipt is entered with reference to the purchase order and will appear in the document flow of the order. Costs and quantities are posted to the order.
- Invoice Receipt.
The invoice is entered with reference to the purchase order and will appear in the document flow of the order. Any invoice differences are automatically credited or debited to the maintenance order.
Internet Catalog
Material planning in the maintenance order can also be carried out using internet catalogs.
It is possible to access an external catalog via the component screen of the maintenance order. The Open Catalog Interface (OCI) interface is available specifically for this purpose, which needs to configured in the IMG in relation to order type and planning plant.
Address Management
You have the option to specify the delivery address for non-stock material in the order, and to transfer it to purchasing. The delivery address can also be derived automatically by using definable rules.
- Functional location
- Equipment
- Notification
- Order
- Components for non-stock material (order)
