We are using f&o, which is integrated with project operation, so there is a challenge in restricting users from feeling timesheets while they are already on leave for that day because we are not getting leave data in project operation.

This is a basic requirement that needs to integrate leave absence with the project ops time sheet, so users are restricted from feeling the time sheet on leave and the same for restricted users to feel leave and absence when they have already filled out the timesheet for the same day.
