Core TSIs : Work Orders : Working with Work Orders : Calculating the Requested completion date
Calculating the Requested completion date
The Requested completion date of an order is calculated from the interval between the priority and the moment of starting an order.
The following fields determine the moment an order is started:
• The Start date-time in case of suborders under a Reservation / Planned maintenance orders / Recurring orders.
• The Planned start date-time in case of orders generated by the Service Scheduler.
• The Reported on (InsertDateTime) or (if populated) Original reporting date-time in any other case.
The following scenarios explain how a company calendar is applied depending on the interval for the priority:
• If the priority interval is in years/months/weeks, non-working days and non-working hours (both normal and deviating) are not taken into account.
• If the priority interval is in days, only non-working days (both normal and deviating) as defined in the applicable calendar are taken into account.
Note  
If the date-time of the field used for calculating the Requested completion date is outside working hours, the first possible date-time within working hours on a working day is used for the calculations.
Similarly, if the calculated requested completion date is outside working hours/days, then it is set to the first possible date-time that is within working hours on a working day.
• If the priority interval is in hours, the calculation is similar to a priority in days. However, non working hours (both normal and deviating) as defined in the applicable calendar are taken into account as well.
• If the priority interval is in minutes, non-working days and non-working hours (both normal and deviating) are not taken into account. This is because for this priority, the work is considered to be so urgent that it should be carried out irrespective of working hours/days.
Note  
If an order is resumed from an 'On hold' status, the Requested completion date is recalculated, even if the SLA is not applied.

Note  
The above scenarios also apply to the calculation of Requested response date-time, Requested date-time to attend and Requested date-time to fix, except that the interval defined in these fields of the SLA is used to determine the period.

For more information on SLAs, refer to SLA Management.
