Issue/Introduction:
We are trying to add Idea using + Work on MUX timesheet and the item is grayed out and says Not Open for Time Entry and cannot be selected.
However it works fine with another option 'Copy previous timesheet'.
We have made sure the 'Open for time entry' is checked on the idea as well as the resources on the team and track mode is set to PPM .
Cause:
This could be because the task got corrupt.
Even though you do not see tasks on NPIOs, there is an effort task created behind the scenes.
Environment:
Release : 15.8
Resolution:
