Check the following:

Update Program (s)

Check this box to update the maintenance program of the part or component with the updated work unit details.

Click the “Cancel Update” pushbutton to cancel the modified details of the work unit.

The system sets the work unit updation number to the “Canceled” status.

Click the “Edit Work Unit Changes” pushbutton to update the work unit details in the part program or component maintenance program.

The system performs the following when you click the “Edit Work Unit Changes” pushbutton:

Updates the work unit details to the component maintenance program if the Component ID is specified. Otherwise it copies the work unit details to the part program.
Sets the status of the “Authorized” part program or CMP as “Fresh” and increments the existing revision number.
Generates the work unit update number as a serial number prefixed and suffixed by the prefix and suffix defined for the selected “Numbering Type”.
If the “Action” field is set to “Overwrite”, the system updates selected expense type of the work unit in the part program and the component program. And, if the “Action” field is set to “Append”, the system adds the expense type selected for the work unit along with the other details in the part program and the component maintenance program.
If the “Action” field is set to “Append” or “Overwrite”, the system calculates the ‘next scheduled date’ for the component maintenance program by adding the threshold value in the part progam to the component induction date. If the threshold value is not available, the system calculates the ‘next scheduled date’ by adding the interval value of the part program to the manufacture date of the component as defined in the “Aircraft” business component. If the manufacture date is not available, the system arrives at the ‘next scheduled date’ by adding the component induction date to the interval value.
The system allows you to overwrite / delete task from the Part Program / Component Program, only if the process parameter “Allow modification of Eng. Doc. task in Maintenance Program” is set as “Allowed” in the “Define Process Entities” activity of the “Common Master” business component.
On addition of task to a Component Maintenance Program, schedules are copied to “Edit Date Based Schedule Information” and “Edit usage Based Schedule Information” page of the current business component. The system updates the computation basis controls ‘Next Due Calc. On’, ‘Calc. Ref. Value / Date’ and ‘Last Schedule Date / Value in these pages, as shown in the below table:

Scenario	Next Due Calc. On	Calc. Ref. Date	Last Schedule Date
If NSD is computed based on ‘Manufactured Date’	Mfr. Date	Corresponding Date	Not Applicable
If NSV is computed based on 'Threshold / Interval Value'	Initial Interval	Threshold / Interval Value	Not Applicable
On addition of a task with 'Initiated / Reset by' set as "Related Task Compliance"	Not Applicable	Not Applicable	Not Applicable
If there are no schedules and for tasks with 'Prog. item Type' "To be Decided"	Blank	Blank	Blank

To proceed, carry out the following

Select the “Edit Date Based Schedules” link at the bottom of the page to modify the date-based schedule details.
Select the “Edit Usage Based Schedules” link at the bottom of the page to modify the usage-based schedule details.

Updating work unit details in programs – An overview
