Use the drop-down list box and set the field to “Required”, if the work center capability check is required. Select “Not Required”, if the work center capability check is not required.

Data selection in this field is mandatory.

Click the “Assign” pushbutton, to assign the work units selected in the multiline to the specified visit package.

Note: This action is workflow-enabled. Notification messages can be sent as per the settings you have defined in the "Workflow Management" business component.

The system performs the following on clicking the “Assign” pushbutton:

The system updates the visit category displayed in the “Visit Category” field, as the plan item group, to all the tasks including the tasks within the standard procedures.
For the work units that are associated with maintenance reports, the system copies all other work units associated with the maintenance report, into the visit package. The system also copies the part and resource requirements identified for all the tasks, sub tasks and standard procedures identified for these work units.
Updates the stock status of all the parts required for the work units, to “Accepted”.

Note: Updates the stock status as “PBH”, if the following conditions are satisfied:

a. If the aircraft is mapped to the supplier as “PBH” and the requested part or its next higher assembly for the aircraft is identified as “PBH” part for the supplier

b. if the component, or the next higher assembly of the component being requested for the component replacement job or on wing job, is identified as “Under PBH” for supplier.

c. If the component’s EIPN (End Item Part Number) is identified as “Under PBH” for the supplier.

Ensures that only Maintenance Reports in ”Analyzed” processing status are assigned to the visit package and updates the “Job Class” of the work units as “Corrective” in the ”Visit Package” business component.

On assignment of the work units with the “Job type” as “Component Removal” to the visit package, the system does the following check:

If the option for auto preclusion of call-outs is set as required in the “Set Options” activity, then system checks whether any component removal jobs already exists for corresponding parent components of the components being assigned now. If so, the system automatically precludes the work unit for the removal of the child component and sets its preclusion status to “Precluded” and the preclusion status of the work unit of the parent component to “Superseded.

On assignment of the work units with the “Job Type” as “On Wing” to the visit package, the system does the following check:

If the option for auto preclusion of on-wing jobs is set as required in the “Set Options” activity, then the system checks whether any on-wing jobs already exists for parent components of the components being assigned now. If so, the system automatically precludes the work unit for the on-wing job of the child component and sets its preclusion status to “Precluded” and the preclusion status of the work unit of the parent component to “Superseded”.

The system assigns the selected work units to the visit package and changes the status of the work units from “Pending” to “Assigned” in their respective sources. If the work unit type is either “Aircraft Work Package” or “Component Work Package”, the system breaks them down into their constituent work units as standard procedures and/or tasks considering the seasonal (off-line) work units and additional work units as defined under expanded work scope of aircraft specific maintenance program.

Note: If the system parameter “Aircraft Workscope: Allocation Revision Method” or “Component Workscope: Allocation Revision Method ” is set as “Modification Log” in the “Set Options” activity, then the details of allocation of respective work units to the visit package is posted in the “Modification Log”. If the system parameter is set as “Direct”, then the details of the allocation are posted directly in the visit package.

To proceed, carry out the following

Select the “View Execution Center Load” link, to view the maintenance activities scheduled for the execution center.
Select the “View Work Center Capability” link, to view the execution capabilities available in the work center for the specified work units.

Note: Select at least one work unit in the multiline, to view the execution center capabilities.

Select the “Set Advanced Search Criteria” link, to set the advanced criteria to search for the work units.

Selecting work units for allocation – An overview

This page allows you to select the work units of a particular aircraft. You can carry out a search based on the filter criteria such as days remaining before the forecasted arising, elapsed time, primary work center, range of compliance, scheduled and alert dates of the work units, and the source of the work units. You can also specify the advanced search ID, which identifies a set of advanced search criteria, to search for the work units.

The system retrieves all the work units of job status "Pending" based upon the filter conditions. You can select these work units to create a new visit package, create deferment request for work units, preclude the work units or assign the selected work units to an existing visit package, which is not in the "Closed" or "Canceled" status and whose visit type is “Planned”. This page also enables you to view the details of the selected work units.
