Mandatory ?	Use the drop-down list box and set the field to “Yes” to indicate that the execution of the work unit is mandatory in the work package. These work units cannot be deleted during execution they can only be deferred. Otherwise set the field to “No”.
Expense Type	Use the drop-down list box to modify the expense type of the work package. The system provides the following options: Revenue – Select this option if the cost incurred on the work unit is due to routine maintenance activity and must be recorded as revenue cost. Capital – Select this option if the cost incurred on the work unit must be recorded as a capital cost.
Job Type	Use the drop-down list box to specify whether the work unit must be performed on the aircraft or on the components fitted to the aircraft. The system provides the following options: Aircraft – Select this option to indicate that the work unit must be performed on the aircraft. Onwing - Select this option to indicate that the work unit must be performed on components attached to the aircraft.
Maintenance Type	Use the drop-down list box to specify the type of maintenance job that must be carried out as a part of the work unit. The system provides the options “Repair”, “Overhaul”, “Inspection” and “Others”. Do not leave this field blank if you have set the “Job Type” field to “Onwing”.
Position Code	The position code in the aircraft where the work unit must be performed (Integer). Ensure that the position code entered here has already been defined for the primary aircraft model and configuration class in the “Maintain aircraft model configuration” activity of the “Configuration” business component and is in “Active” status. Help facility available
Level Code	The number identifying the level for the position code that occurs in the primary model (Decimal). Ensure that the level code entered here has already been defined for the primary aircraft model and configuration class in the “Maintain Aircraft Model Configuration” activity of the “Configuration” business component and is in “Active” status.

Note: Ensure that you enter either the position code in the “Position Code” field or the level code in the “Level #” field if you have selected “Onwing” in the “Job Type” field. If you have entered both the position code and the level code, ensure that it is a valid combination defined for the primary aircraft model and configuration class in the “Maintain Aircraft Model Configuration” activity of the “Configuration” business component.

Note: If the position code alone is entered and it is unique in the configuration, the system retrieves the level code corresponding to the position code.

If the level code alone is entered, the system retrieves the position code corresponding to the level code.

If you have entered both the position code and the level code, ensure that it is a valid combination.

Starting Day	The starting day for executing the work unit (Integer). Ensure that the value entered here is positive and is greater than zero.
Other References	Any other references based on which the work unit is specified for the work package (Alphanumeric, 255).

The system fills in the following fields on clicking the “Edit Work Package” pushbutton:

Work Unit Desc	The textual description of the work unit.
Work Center Description	The description of the work center.

Check the box in the multiline to mark the work unit for deletion.
Click Delete icon in the toolbar above the multiline to delete the selected work unit.

Note: While deleting a work unit in the multiline, if the “Resolve Relationship” box is checked, the system automatically assigns a “Finish – Start” relationship between the work units preceding and succeeding the work unit being deleted. If the “Resolve Relationship” box is left blank, the system deletes the work unit and the relationship with its preceding and succeeding work units. If the work unit being deleted has only preceding work units, or only succeeding work units, the “Resolve Relationship” box does not have any significance.

To illustrate, let us consider Task T1 as predecessor to Task T2 and Task T2 as predecessor to Task T3. If Task T2 is marked for deletion, the system identifies Task T1 as a predecessor to Task T3 and establishes a Finish-Start relationship between tasks T1 and T3. If a relationship is already defined between T1 and T3, then the system retains that relationship.

If you wish to insert work units in the multiline and assign sequence numbers for them, select 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 work unit.
Click the “Edit Work Package” pushbutton to update the modified work package information.

Note: Ensure that atleast one record is available in the multiline.

Click the “Import From PMT” pushbutton to schedule the details of the maintenance program through the project management software.

Modifying the work package details in the maintenance program – An overview

Work packages are effectively used to group the maintenance activities that have the same periodicity (repeat interval). The various types of routine aircraft maintenance such as daily and weekly inspections, major checks etc. can be configured as standard work packages.

The standard work package can be modified at the maintenance program level, i.e. new tasks can be added or existing tasks deleted from the work package.

You can select the work package that is included to the maintenance program and you can specify the work center where the work package must be carried out and the execution time details for completing the work package can also be specified. You can also specify whether the relationship must be resolved when a work unit is deleted from the multiline.

Tasks and standard procedures included in the work package can be termed as work units. You can include multiple work units to the work package in the “Work Package Detail” multiline and specify the sequence in which they have to be carried out while executing the work package. You can also provide the work center where the work unit has to be performed.

Note: if the work center is not specified for the work unit in the multiline then the system will assume the work center that is specified for the work package.

The estimated time and estimated man-hours for completing the work unit can also be specified. You can specify which work unit has to be given priority when two work unit conflicts while performing the work package. If the work unit is specified mandatory then the work unit cannot be terminated unless the work unit is completed or deferred. Otherwise the work package can be terminated even if the work unit is not performed.

The system updates the details of the work package in the program and sets the “Last Modified Date” and to the server date.
