The manage task to accept job owners dates function is used if you have a number of tasks in requested or booked in status and they are now old so they can be 'cleaned up' by using the 'Manage' button.

This can be done in bulk by the primary account user in the requested or booked in task lists pages or 1 by 1 in the task details pages by the assigned user.

Step-by-step guide

IN BULK:

Login
Go to the Requested or Booked In Task List
Click on the 'Manage all requested tasks' or the 'Manage all booked in tasks' button at the top LHS of the list
In the popup window click yes.

1 BY 1:

Login
Go to the Requested or Booked In Task List
Select a task that you want to manage
In the task details page click on the 'Manage' button (tick)
In the popup window click yes.

You will receive an onscreen notification to confirm that you have successfully managed the task/s.

Now you can still further progress these tasks now if you need to by opening each one individually and making the changes required.
