If you wish to insert tasks in the multiline and assign sequence number for them, click the “Re Number” pushbutton to rearrange the existing rows in the ascending order of the sequence number. The system regenerates the sequence number in multiples of five, thereby enabling you to specify the sequence number for the newly added task.

Click the “Get Related Tasks” pushbutton to retrieve the following:

If no task is selected in the multiline, the system retrieves all the child related tasks.
If a task is selected in the multiline, the system retrieves the child related tasks specific to the selected task, with Execution relationship defined as “Concurrent Group”, “Concurrent Specific” and “Concurrent Conditional”.

The “Predecessor Constrained” tasks will not be retrieved in the multiline. The count of the child related tasks is displayed as “Unprocessed Rel. Task”.

Unprocessed Rel. Task:

For the related tasks retrieved in the multiline, the system identifies all the child related tasks with Execution relationship defined as “Concurrent Group”, “Concurrent Specific” and “Concurrent Conditional”. The related tasks which are already available in the multiline are eliminated and the remaining number of child tasks is displayed as “Unprocessed Rel. Task”.

Example:

Let the Primary Task be ‘T1’ in the Repair Scheme.

Let the Related Tasks retrieved in the multiline be ‘T2’, ‘T3’ and ‘T7’.

If the Related Task ‘T2’ has its child tasks as ‘T3’, ‘T4’ and ‘T5’, the “Unprocessed Rel. Task” is displayed as 2. (i.e. T4, T5). (The child task ‘T3’ is not considered because it is already available in the multiline).

Click the Delete icon in the tool bar above the multiline, to delete the repair scheme details selected in the multiline.

Note: When the related task is deleted from the multiline, all its child tasks also get deleted.

Click the “Maintain Repair Scheme” pushbutton to maintain repair scheme for the tasks.

Note: The system displays an error message, if any other concurrent user attempts to update the repair scheme details.

Note: If the process parameter “Automatic update of Task-Part effectivity based on Repair Scheme Definition” is set as ‘1’(Required) in the Define Process Entities activity of the Common Master business component, then the system automatically updates the effectivity list of the child Task(s) with the Position Part # and its alternate Part # if they do not exist already.

If the process parameter “Automatic update of Task-Part effectivity based on Repair Scheme Definition” is set as ‘1’(Required) in the “Define Process Entities” activity of the “Common Master” business component and ‘Effective for Alternates’ is selected as ‘Yes’ in the “Task Detail” section, then the system automatically updates the effectivity list of the Repair Scheme Task with this specific repair scheme Part # and its alternate Part # if they do not exist already.

If the process parameter “Automatic update of Task-Part effectivity based on Repair Scheme Definition” is set as ‘1’(Required) in the “Define Process Entities” activity of the “Common Master” business component and ‘Effective for Alternates’ is selected as ‘Yes’ in the “Repair Scheme Details” multiline, then the system automatically updates the effectivity list of the child Task with this child Part # and its alternate Part # if they do not exist already.

The system generates Task Control #, on addition of new tasks.

The system creates a repair scheme for the tasks, if the task relationship with the primary task is already defined in the “Maintain Task Relationship” page. If the relationship does not exist with the primary task, system creates “Concurrent – Specific” relationship between the primary task and the related task for creating the repair scheme.

Maintain Repair Scheme – An overview

In this page, you can create a repair scheme for the tasks by grouping the tasks based on the need of users, MRO, operator, etc. Grouping of the tasks can be done at model level or part level. You can specify the sequence in which the tasks must be executed. You can also specify the execution priority of the tasks and select the work center in which the task must be executed.

You can retrieve repair related tasks which are specific or not specific for any Operator Code or Maintenance Object (Aircraft Model # or Part #). You can specify various details of the task such as Relationship Type, Child Position #, Child Part #, Manufacturer #, Execution Facility for the repair of the part, Work Center in which the task must be executed, Repair Classification, Execution Priority, etc.

This page facilitates the user to perform the following:

Create a repair scheme by grouping the tasks based on need of users / MRO need / operator need.
Group tasks at part level / model level.
Perform master sequencing of tasks.
Automation of the tasks.
Eliminate duplication of sequence number of task.

You can insert tasks in the multiline and assign sequence number for them, by clicking the “Re Number” pushbutton to rearrange the existing rows in the ascending order of the sequence number. The system regenerates the sequence number in multiples of five, thereby enabling you to specify the sequence number for the newly added task.

For the related tasks retrieved in the multiline, you can retrieve all the child related tasks with Execution relationship defined as “Concurrent Group”, “Concurrent Specific” and “Concurrent Conditional”. The count of the tasks retrieved is displayed as “Unprocessed Rel. Task”.
