The system displays the following fields in the “Work Unit Details” group box:

Aircraft Reg #	The registration number of the aircraft
Work Center #	The code identifying the work center where the work unit is allocated for execution
Work Unit #	The work unit which will be precluded against a suitable higher maintenance job, allocated to a visit package
Work Unit Type	The type of the work unit, which could be “Task”, “Standard Procedure” or “Work Package”
Schedule Date	The date on which the work unit is expected to get executed
Latest Compliance Date	The date beyond which the work unit execution cannot be postponed

Enter the following fields in the “Search Criteria” group box:

Work Unit #	The number that identifies the work unit of higher maintenance level that is a part of a visit package (Alphanumeric, 40). You can enter the work unit number in full or specify it partially using the “*” character. The system retrieves all the work units that are similar to the value specified here. Leave this field blank to retrieve all the work units of job type "Aircraft", status as "Allocated" and whose transient status is not "Pending Deferrals" or "Precluded".
Work Unit Type	Use the drop-down list box to specify the type of the work unit. The system lists the options, “Task”, “standard Procedure” and “Work Package”. The system retrieves all the work units of the type specified here. Leave this field blank to retrieve the work units, irrespective of the type.
Work Unit Desc	The textual description of the work unit (Alphanumeric, 150) You can enter the work unit description in full or specify it partially using the “*” character. The system retrieves all the work units whose descriptions are similar to the value specified here. Leave this field blank to search for the work units, irrespective of the description.

The system retrieves all the visit packages that are similar to the value specified here. Leave this field blank to search for all the visit packages.
Primary Work Center #	Use the drop-down list box to select the work center with which the work unit is associated. The system retrieves all the work units associated with the selected work center selected here. Leave this field blank to retrieve all the work units irrespective of the work center.
Schedule Date Till	The scheduled date of the work unit (Date Format). The system retrieves all the aircraft work units whose schedule date is earlier or equal to the specified date.
Execution Unit	Use the drop-down list box to select the organization unit to which the visit package (in which the higher level maintenance job is listed) is allocated.

Click the “Search” pushbutton, to search for the work units.

The system displays the following in the “Search Results” multiline:

Work Unit #	The work unit retrieved by the system
Work Unit Desc	The textual description of the work unit
Work Unit Type	The type of the work unit, which could be “Task”, “Standard Procedure” or “Work Package”
Earliest Compliance Date	The earliest incidence of the maintenance activity on the specified aircraft
Schedule Date	The date on which the work unit is scheduled to be executed
Latest Compliance Date	The latest incidence of the maintenance activity on the specified aircraft
Work Center #	The code identifying the work center to which the work unit is allocated
Est. Man Hrs.	The estimated time required, in man-hours, for the completion of the visit package

Comments

Any additional remarks pertaining to the precluding of the work units (Alphanumeric, 255)

Note: Ensure that only one work unit is selected for preclusion. Also ensure that the job type of the selected work unit is “Aircraft” and the job status is “Allocated”.

Check the box in the “Select” column of the multiline, to select the work unit, which will be the superseding work unit to the precluded work unit.
Click the “Preclude Work Unit” pushbutton, to preclude the work unit in the header.

The system sets the “Precluded WU Status” of the work unit selected in the multiline as "Superseding" and the “Precluded WU Status” for the work unit in the header as “Precluded”.

To proceed carry out the following

Select a visit package in the multiline, and select the “View Precluded Work Unit Details” link at the bottom of the page, to view the precluded work units of the visit package.

What you can do in this page

Preclude a work unit

You can preclude a work unit that is superfluous. A work unit becomes superfluous when a work unit of higher level maintenance is allocated to a visit package. The precluded work unit will not be executed.

Specify the filter criteria to search for the superseding work unit.
Click the “Search” pushbutton.
Select only one superseding work unit in the “Search Results” multiline.
Click the “Preclude Work Unit” pushbutton, to preclude the work unit in the header.

The system sets the “Precluded WU Status” of the work unit selected in the multiline as "Superseding" and the “Precluded WU Status” for the work unit in the header as “Precluded”.

Precluding work units – An overview

This page allows you to preclude work units. The execution of certain work units becomes unnecessary due to the execution of a higher-level maintenance activity. For example, a work unit (W01) for the inspection of a component becomes unnecessary, if there is a work unit (W02) in a visit package for the overhaul of the same component. In such situations, to prevent wastage of time, resource and redundancy in maintenance activity, the work unit (W01) is precluded against the work unit (W02). The precluded work unit (W01) will not be performed.

You can preclude a work unit, whose job status is “Pending” and is of job type “Aircraft”. Ensure that the source of the work unit to be precluded is not component forecast.
