Why am I unable to change the dates on which a labor schedule version is active?

When you edit an active labor schedule version, you cannot update the dates on which it is active because the labor schedule version is still distributing payroll costs.

Editing labor schedule versions while they are still distributing payroll costs could impact running distribution processes.

Before you can update the dates on which an active labor schedule version is active, you must deactivate the labor schedule version by changing its Status to Inactive.

You can then edit the deactivated labor schedule version and update its Start and End dates as required. Once you're satisifed with your updates, you can reactivate the labor schedule version.
Note:

You must ensure that expenditure item dates associated with costs that have already been distributed using this labor schedule version continue to be between the updated start and end dates.
