Features of the Sub-Operation 

Operations and sub-operations sometimes have different features. You should note the following features for sub-operations:

The numbers of the sub-operations determine the sequence in which they are performed.

You can assign a control key to each sub-operation.

You cannot assign any material components or maintenance packages to sub-operations.

The sub-operations are relevant for capacity planning and costing of the maintenance orders in which the task lists are included. The work is used for capacity planning instead of the work specified in the operation.

This data in the sub-operation is purely for information. The duration specified in the operation is always relevant for order scheduling after the task list has been canceled. However, you can plan the sub-operations within the schedule relative to the start or end of the corresponding operation.

This is used for cost accounting instead of the activity type specified in the operation.

Example of the importance of duration and work.

The duration of an operation is two days, because the performance of the tasks specified in the sub-operations takes up this time. For the engineer that planned the tasks for an hour, the work in the corresponding sub-operation takes one hour.
