The integration of SAP S/4HANA Asset Management with production planning and controlling in SAP S/4HANA involves four elements.
- You can use technical object master data to create a cross-reference to the work center as a production planning resource.
- You can display scheduled maintenance orders in the production planning board.
- You can use production orders to create your own spare parts.
- You can make the maintenance work center aware of specific procedures or suborders for production orders.
Work Center
In the master data of a technical object, whether it’s a functional location or equipment, you will find the Work center field in the Location data field group.
This work center is often confused with the work center responsible for maintenance activities. However, you use the Main WorkCtr field in the Responsibilities field group for this purpose. In contrast, the Work center field serves as a cross-reference. It identifies the production planning work center, and thus the production capacity resource, that corresponds to this functional location or equipment.
Not All Work Centers Are Created Equal
By assigning a technical object to the work center, you create a cross-connection to production planning. The main work center is the workshop responsible for maintenance activities. A 1:n relationship exists here: several technical objects can be assigned to a production planning work center.
Available Capacity Cannot Be Calculated Automatically
The number of individual capacities in the production planning work center, which is a key factor in determining the capacity that production planning can offer, is not calculated from the number of assigned technical objects.
Simply assigning a technical object to a work center is initially only a cross-reference; it doesn’t create any reservations, capacity loads, or similar effects when a maintenance order for that technical object is pending.
Maintenance Orders in the Production Planning Board
If you want maintenance tasks to influence production planning, you must first meet the following prerequisites:
- Assign the technical object to a work center.
- Use the Customizing function Create System Conditions or Operating Conditions to define an operating condition for which the Reservation by PM option is activated.
If you want to make your SAP S/4HANA Asset Management order visible in production planning, enter an appropriate value in the SystCond. field of the order header, as shown in the figure below. This assignment is possible both in Transaction IW31 (and subsequent) and in the SAP Fiori apps.
The upper part of the production planning board (Transaction CM21 [Capacity Leveling]) now displays the maintenance orders scheduled for this resource by plant maintenance, including the production orders of the resource.
However, you’ll see only the maintenance orders that require machine downtime, that is, those for which the system condition indicator is set to Reservation. The production planning board does not display maintenance orders that can be performed during production and for which you have not set the system condition indicator.
Showing Maintenance Orders in the Production Planning Board
Showing maintenance orders in the production planning board serves only as an indication to production that plant maintenance has scheduled an order on the date. No automatic load or block of the production resource occurs. If the date cannot be met from the production perspective, manual communication must occur between production and plant maintenance.
However, the production scheduler cannot change the maintenance order from the production planning board. The scheduler cannot reschedule it, for example, if production cannot release the resource on that date for maintenance tasks.
In-House Production of Spare Parts
Maintenance orders sometimes require spare parts that can’t or shouldn’t be procured externally. Instead, these parts must be manufactured in-house by the plant maintenance or production department.
To begin this process, create a production order (Transaction CO01 [Production Order Create]) for the spare part. In addition to the general transaction and material planning information, you enter the maintenance order as the settlement rule.
Assigning a Production Order to a Maintenance Order
When you manufacture your own spare parts, you create a production order. The costs generated by the production order are visible in the maintenance order. The costs are settled to the maintenance order and are indicated in the technical object’s history.
After the spare part is finished, you settle the production order to the maintenance order (Transaction KO88 [Actual Settlement Order]).
Maintenance Services for Production
The opposite situation occurs when plant maintenance performs services as part of production orders, for example, retooling, rebuilding, and similar activities.
You schedule the maintenance order and enter the production order as the settlement rule.
Assigning a Maintenance Order to a Production Order
When plant maintenance performs services in the context of production, you create a maintenance order that you then settle to a production order. After the maintenance order is settled, the costs incurred in plant maintenance are visible in the production order and become part of follow-up calculations for the product.
Always Settle Suborders First
Make sure that the subordinate order is always settled and closed first from an organizational and technical perspective.
Conclusion
The integration between SAP S/4HANA Asset Management and production planning is not a peripheral configuration exercise; it reflects a fundamental operational reality that maintenance and production are deeply intertwined. By linking technical objects to production work centers, surfacing maintenance orders in the planning board, enabling in-house spare parts manufacturing, and allowing costs to flow between maintenance and production orders, SAP S/4HANA gives organizations the tools to treat these functions as collaborators rather than competitors for the same resources. The result is greater transparency across the shop floor, cleaner cost tracking, and a stronger foundation for decisions that affect both equipment reliability and production throughput.
