Requirement to execute a maintenance task at a maintenance object on a specific date.

In addition, the maintenance order is a means of documenting maintenance tasks.

In particular, the order is used to:

• Plan tasks specifically

• Monitor the execution of tasks

• Enter and settle the costs incurred by tasks

The order data is entered in the maintenance history. This data is extremely important for evaluations and future planning.

An order contains operations that describe the individual work steps. If greater detail is required, operations can be sub-divided into sub-operations.

Operations can be performed sequentially, in parallel or overlapping with one another. Their chronological sequence is defined by relationships. Operations and sub-operations can be processed internally or externally.

An operation or sub-operation to be processed internally refers to a work center that is responsible for performing the work. The necessary capacity requirements can be planned, in order to perform the operation or sub-operation.
