In capacity leveling you can display plant maintenance tasks at work centers. You can lock work centers where the plant maintenance tasks are carried out thus preventing operations being dispatched there for the duration of the plant maintenance.
To do this you have to make an appropriate entry in the header of the plant maintenance order for the system condition. A capacity requirement is generated for the work center where the plant maintenance task is carried out.
In the SAP standard a black bar is displayed in the capacity planning table for the duration of the maintenance task at this work center. In the lists for the extended evaluation and in the planning table (tabular form) the maintenance tasks are visible from the maintenance tasks at the work centers.
