A solve is what we call a roster built by Auto Assign. Once you have added your shift patterns and hit Auto assign, CoRoster will work to fit people to shifts using your shift rules and employee preferences.

If someone can't be found to work based on your rules, your solve may not have all shifts filled but that's OK. (For more information on why that might happen see here)

Unfilled shifts clearly show up, allowing an administrator to manually allocate staff to shifts.
