Stopping, Delaying and Replanning Work Order Operations

This document explains how work order operations can be modified in different ways. This could mean stopping the operation for different reasons, delaying the operation or replanning the operation. It can also mean deferring the operation to a different time.

Use this process when you need to make adjustments to operations in progress.


The work order can be stopped, put on hold, rescheduled to new date and/or facility, replanned to materials, tools, permits or employees.

The work order may be processed according to the new conditions. This could be for example:

Before you start

The starting conditions listed in Performing Maintenance should be met.

Follow These Steps

  1. Add Employees, Permits, Skills, Tools and Materials to a WO Operation

    Use these activities to add employees, permits, skills, tools and materials to a work order operation. The activities are used to replan operations that are in progress. This can be the case for example when a different employee than the one originally planned for the operation performs the work.

    See the respective instruction for information about where to perform these activities.

  2. Allocate Persons to a WO Operation

    Use these activities to allocate persons to the operation in progress. Persons can be allocated either manually or by multiple choice. Use manual allocation when you want the system to allocate a person. Use multiple choice allocation when you want to allocate several employees to the same operation. This is done to allow the first available employee to log on to the operation.

    See the respective instruction for information about where to perform these activities.

  3. Delete Work Orders and Operations

    Use these activities to delete entire work orders or work order operations. Delete work orders and operations is necessary when the work is not going to be performed, for example if there was no problem found and therefore no action is necessary.

    Delete work orders in 'Work Order. Open' (MOS100).

    Delete WO operations in 'Work Order. Open Line' (MOS101) or 'Work Schedule. Open Toolbox' (MOS195).

  4. Hold or Stop Work Orders and Report Interruption Start

    Use these activities to stop a work order for different reasons. The work order can be stopped to indicate that work on the operation has finished. It can be held to make additional capacity available for other work orders and it can be interrupted due to different problems, such as tool or material shortages.

    Work orders are held in 'Work Order. Open' (MOS100) or 'Work Schedule. Open Toolbox' (MOS195).

    WO operation stop is reported in (MOS821).

    Interruption start is reported in 'WO Operation. Report Interruption Start' (MOS822).

  5. Reset Stopped Work Order

    Use this activity to unlock work orders that have become stuck in status X2. This is done in order to get the WO status to return to status X0.

    Reset the work order in 'Work Order. Open' (MOS100).

  6. Defer Work Order

    Use this activity when a work order needs to be deferred. This can be necessary when the work cannot be performed on the original time. The deferral process deletes the work order and re-creates it as a work request.

    Work orders are deferred in 'Work Order. Defer' (MOS031).

    For a work order referring to a non-scheduled service it is possible to set a new start date during deferral. For a work order referring to a scheduled service, you can change the start date manually in 'Work Request. Open' (MOS170) or the due meter values in 'Concession. Open' (FLS040).

    For merged work orders, that is, a work order referring to several services, you need to defer the services instead. This is done in 'Equipment. Open Service History' (MOS180).
