Change Work Scope

Explanation

Use this activity to change and release the work scope when new maintenance tasks (modifications or LLPs) are transferred from IFS/Vehicle Information Management (VIM) and the work scope is already released and when an interim order structure is created for the maintenance overhaul object (work order part). There are several cases when these late works scope changes are necessary.

• One case is when new modifications or life limited tasks with affected parts are transferred to work scope the maintenance levels assigned does not expose the affected parts correctly. The maintenance levels have to be changed to expose these new affected parts in order to perform modifications on repair shop orders.
  
• Another case of change in work scope is 'Different part found' while disposition causes more modifications, and this exposes different affected parts and maintenance levels are changed to accommodate this. This is also the case is when at the time of disposition the inspector sees more problems on the sub-assembly which will need to change maintenance level to disassemble more from the sub-assembly.
  
• Change in work scope can also occur when a sub-assembly at the time of disposition requires more or less disassembly, as a result of inspection and disposition Then a new maintenance level needs to be assigned. When maintenance levels are changed and release work scope activity is performed then the old interim order structure and the new interim order structure are compared to effect the changes to the interim order structure.

If new tasks are transferred after the interim order structure is released and shop orders are created then the new tasks also needs to be approved. This approval will set the state of the tasks to Added. The state Added is used to distinguish these new tasks from the previous ones that are in state Original after the release of work scope.

Prerequisites

• New tasks (Modifications and LLPs) transferred for an already released works scope.

System Effects

• There will be new tasks in state Added.

Procedure

Change Work Scope:

1. Open Define Work Scope window and select the appropriate work order for which you want to change the work scope. 
2. Investigate how the new transferred tasks in the Work Scope Tasks tab and in Define Work Scope/Affected Part Tasks sub tab will affect the released work scope. Also check for affected parts in Assign Maintenance Levels sub tab.
3. Reset maintenance level for the sub-assembly levels affected by the change. Either clear each maintenance level for the affected sub-assembly parts, in the first Assign Maintenance Level sub tab right-click and then click on Reset Maintenance Level or clear all maintenance levels for the entire disassembly structure, when you right click on the header section of the Define Work Scope window and click on Reset All Maintenance Levels. 
4. Now assign the new maintenance level based on the information from the previous steps, right-click and then click on Set Maintenance Level.
5. Approve the new tasks, right-click and the click on Approve All Tasks.
6. Release the changed work scope.

Note: Re-releasing the work scope effects only the interim order structure. You must re-release the interim order structure to propagate any changes to the supply shop orders. Generally, you re-release because you need to either increase or decrease the work scope. Where the interim order structure has not been previously released, both increases and decreases to the work scope are permitted. In this case, a re-release of work scope simply deletes and re-creates the interim order structure.

However, where the interim order structure has been fully or partially released, work scope increases are not always permitted. In these cases, the status of the supply shop orders determines if work scope reductions can occur. If the supply or parent supply shop orders are in Released or Reserved status, work scope reductions are permitted. If the supply shop orders are in the Started status or after, work scope reductions are prohibited. In this case, a message will appear, and you will need to adjust the maintenance levels for the work scope, and re-release it. You can view any errors in the Define Work Scope/Define Work Scope/Log Details window.

If an error occurs during the re-release of a work scope, the interim order structure will not being updated at all. For example, if three maintenance level changes are made, all of which reduce work scope, and one of these changes generates an error, none of the changes in the interim order structure will be made. When errors occur on a re-release, the maintenance levels in the work scope will not match the maintenance levels associated with the interim order structure. This is something you should correct manually, to keep the work scope and interim order structure in sync.

When a work scope re-release occurs without errors, the interim order structure will contain a combination of new and modified interim orders. You must release these new and modified interim orders to create new or modify existing supply shop orders.

You can also verify the changes in the interim orders structure and also if necessary on the disassembly, disposition and repair shop order.
