On addition of task, schedules are copied from 'Task Master'. Based on the Schedule Type and the schedules copied, the system updates the computation basis controls ‘Next Due Calc. On’, ‘Calc. Ref. Value / Date’ and ‘Last Schedule Date / Value’ in “Edit Date Based Schedule Information” and “Edit usage Based Schedule Information” page of the current business component. This is show 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 no schedules are copied and for tasks with 'Prog. item Type' "To be Decided"	Blank	Blank	Blank

On addition of ‘One time’ / ‘Recurring’ task, if the task exists in “Maintenance Task” business component, the system computes Next Schedule Date (NSD) and Next Schedule Value (NSV) as follows, based on the value of ‘Reset on Attachment?’:

Reset On Attachment	NSD	NSV
Not Required	NSD = Threshold value + Mfr. Date / Induction date	NSV = Threshold Value
First Attachment	NSD = Threshold value + Component Attachment date and time. If the component is not attached in an Aircraft, NSD is updated as Blank.	NSV = Threshold Value
Every Attachment	NSD = Threshold value + Component Attachment date and time. If the component is not attached in an Aircraft, NSD is updated as Blank.	NSV = Threshold Value + Parameter value on Component Attachment date and time If the component is not attached in an Aircraft, NSV is updated as Blank.

Process Parameter dependency: If the process parameter “Auto Activation/Inactivation of schedule status of tasks in CMP based on Maint. Operator change?” is set as 1 for Yes under the entity type “Tech. Records Process Ctr” and the entity “Part Prog in the “Define Process Entities” activity of Common Master, the system automatically activates Schedule Status of the tasks mapped to the maintenance operator associated with the component in the maintenance program. Further, Schedule Status of the tasks not related to the maintenance operator will be set as Inactive in the component maintenance program. However, if “Auto Activation/Inactivation of schedule status of tasks in CMP based on Maint. Operator change?” is set as 0 for No, Schedule Status of the tasks will not be dependent on the maintenance operator.
