To control planned start/finish time of service order (activity)

Global SRP and the edit options on the graphical planning board controls these dates.

You can replan as follows:

Shift the service order on the graphical planning board.
Change the planned start or finish date of the service order in the Service Orders (tssoc2100m000) session.
Select the Replan check box in the Service Order Resource Planning (tssoc2260m000) session, if you run the global SRP.

The following restrictions to change the planned start date of a service order apply:

You can shift the service order between the limits of the planned start and latest finish dates.
You cannot plan the start date before the current date.

If the planned start date of a service order activity is changed, the planned finish date is determined by the service order activity duration and by checking the calendar data.

If you change the start date of an activity, LN checks if the planned start and finish dates of the service order must be changed. The planned start date of the service order is the earliest planned start date of the service order activity that is related to the service order. The planned finish date of the service order is the latest planned finish date of the service order activity that is related to the service order.

Note: You can replan the service order if the status is Free, Planned, or Released. If the start date changes for an existing service order, LN recalculates the planned start and finish dates of all the related activities.
