The system retrieves those position based schedules that are in the status you specify here. To retrieve position based schedules irrespective of their status, do not specify any status.

Click the “Search” pushbutton to display the search result.

The system retrieves the schedule details for the position and part number of alternate parts identified for the position code and reference part number as defined in the “Configuration” and “Part Administration” components.

Note: If the option setting “Planner Group Security” is set as “Required” in the Set Options activity, then the system retrieves only those parts associated to the Planner group to which the login user has been mapped.

The system displays the following in the “Position – Part # Details” multiline based on the filter criteria specified:

Aircraft Model #	The number identifying the aircraft model with which the position code is associated.
Configuration Class	The configuration class associated with the aircraft model.
Level Code	The level number of the position code and its associated part number.
Position Code	The position code retrieved by the system.
Part #	The number identifying the part associated with the position code.
ATA #	The ATA chapter number associated with the position code
Schedule Status	The schedule status of the position code, such as "Fresh", "Active" or "Inactive".
Schedule Flag	Indicates whether the schedule details have been defined for the position code and the part number. The system displays “Yes” if the date-based or usage-based schedule detail is entered. Otherwise it leaves the field blank.
Part Description	The short name or description of the part.
Schedule Status	The schedule status of the position code, such as "Fresh", "Active" or "Inactive".
Updated By	The name of the user who last updated the position code schedule details.

Enter the following:

Inherit changes to attached Components

Check the box to update maintenance programs of all attached components based on the changes made in the position based schedule. Conversely, leave the box unchecked, if you do not want any change in the maintenance programs of attached components.

Note: Ensure that at least one position code is selected in the multiline.

Check the box in the multiline to mark those position codes that you want to make active/inactive.

To activate position based schedules

Click the “Activate Schedules” pushbutton.

The system saves all changes made to the position based schedules prior to activation and resets the Schedule Status to ”Active”.
If you have selected the “Inherit changes to attached Components” check box, on activation, the system updates the maintenance programs of all the components currently attached to the position to the position base schedules. The system updates component maintenance programs in “Active” status and “Fresh” status as well.
Computation of Next Schedule Value / Date:
The schedules (Next Schedule Date and Next Schedule Value) are calculated for ‘One time’ and ‘Recurring’ tasks, as follows:

Reset On Attachment	NSD	NSV
Not Required	NSD = Threshold value in Position Based Schedules + Mfr. Date / Induction date For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.	NSV = Threshold Value in Position Based Schedules For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.
First Attachment	NSD = Threshold value in Position Based Schedules + Last Installation Date of the component. For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.	NSV = Threshold Value in Position Based Schedules For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.
Every Attachment	NSD = Threshold value in Position Based Schedules + Last Installation Date of the component. For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.	NSV = Threshold Value in Position Based Schedules + Parameter value on Last Installation date of component For Recurring tasks, if Threshold is not defined, ‘Interval’ is considered.

The system retains user-specified NSD/NSV of attached components during inheritance of the position based schedules on the basis of the process parameter ‘Retain manually corrected Next Due Date & Value for the component task when the position based schedule is inherited if LPD & LPV is not available' defined under the entity type “Next Due Computation Logic” and entity "Maint. Program and Forecasting Options" in the Define Process Entities activity of Common Master. The impact of the process parameter during inheritance is explained here:

Process parameter value	Impact on inheritance of position based schedules by attached components
1	NSD / NSV, if manually specified by users in the maintenance program of the attached components are retained in the absence of LPD and LPV
0	The position based schedules overwrite the maintenance program schedules of attached components

To inactivate position based schedules

Click the “Inactivate Schedules” pushbutton.
The system saves all changes made to the position based schedules prior to inactivation and sets the Schedule Status of the position code to ”Inactive”.

Note: You can inactivate only those position based schedules that are in “Fresh” or “Active” status.

If you have selected the “Inherit changes to attached Components” check box, for the position-part # combination being inactivated, determine all the attached components from the interacting “Configuration” business component. If the option 'Schedule impact on Position Change’ is set as “Reset to Template Schedules” in the “Set Options” activity of the current business component, the system copies the Schedules for the Tasks from the Part Program in 'Active' status and updates the Position schedule in the corresponding Component Maintenance Programs all the attached component. The NSD and NSV are calculated for ‘One Time’ and ‘Recurring’ tasks, as follows:

Reset On Attachment	NSD	NSV
Not Required	NSD = Threshold value in Part Program Schedules + Mfr. Date / Induction date For Recurring tasks, if Threshold is not defined, ‘Interval’ in Part Program Schedules is considered.	NSV = Threshold Value in Position Based Schedules For Recurring tasks, if Threshold is not defined, ‘Interval’ Position Based Schedules is considered.
First Attachment	NSD = Threshold value in Part Program Schedules + Last Installation Date of the component. For Recurring tasks, if Threshold is not defined, ‘Interval’ in Part Program Schedules is considered.	NSV = Threshold Value in Position Based Schedules For Recurring tasks, if Threshold is not defined, ‘Interval’ in Part Program Schedules is considered.
Every Attachment	NSD = Threshold value in Position Based Schedules + Last Installation Date of the component. For Recurring tasks, if Threshold is not defined, ‘Interval’ in Position Based Schedules is considered.	NSV = Threshold Value in Position Based Schedules + Parameter value on Last Installation date of component For Recurring tasks, if Threshold is not defined, ‘Interval’ in Position Based Schedules is considered is considered.

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.

Activating position-based schedule information - An overview

In this page, you can search for the position code for which the schedule information is to be activated. You can specify the filter criteria such as the aircraft model, configuration class, level code, position code, part number or ATA chapter with which the position code is associated. Based on the search criteria specified, the system displays the position code and the associated part number details.

You can activate the position-based schedule details in bulk or select a particular position-based schedule to be activated. The system sets the status of the schedule for the position code as “Active" and stores the name of the currently logged in user and the current server date.

Implications of position based schedules on component replacement

At the time of component replacement, when a component is attached to a position in an aircraft, the system resets the component maintenance program in the following way.

Scenarios1: If position based schedules exist for the position in “Active” status (Schedule Status = “Active”), the component maintenance program is updated to the position based schedules. However, if position based schedules for a task do not exist, the system retains the exiting schedule.

Scenario 2: If the position based schedules do not exist or if the position based schedules exist in “Fresh” or “Inactive” status (Schedule Status = “Inactive”), the system looks for the position based schedules for the position to which the component was previously attached. If the position based schedules are available and if the Sch. Impact on Position Change is set as “Retain Existing Schedules” in the Set Options activity of the Component Maintenance Program component, maintenance programs are retained in their present form. If the Sch. Impact on Position Change is set as “Reset to Template Schedules”, the component maintenance program is reset to the part program or the part # of the component. The Next Schedule Date/ Next Schedule Value for each of the tasks are compute an updated in the component maintenance program.

Scenario 3: If position based schedules for the position to which the component was previously attached are not available, the system retains the component maintenance programs.
