When an employee is working on multiple crews on the same day, when foreman 1 submits his crew timesheet it looks like foreman 2 cannot enter or submit his crew timesheet?
This issue should only come up when an individual employee's entire timesheet is submitted and locked on the Timesheets tab.
When this happens you will have a warning message at the top of the Crew Timesheet saying " Some rows are locked as the entries (or timesheets) have been submitted."
The system does allow for the entry and submission of one employee's time on multiple crews in the same day. When an employee is on two different crews, and the foreman for crew 1 does a daily submit of the crew'a time, the employee's underlying individual timesheet always remains open or unlocked for his time to be entered and submitted by another crew's foreman.
