element PreAssignments

Documentation

Preassigned Shifts (or Tasks) that must be in the final solution. Fixed assignments override other constraints like valid task or shift types or break configurations. A violation of hard constraints by fixed assignments does not make a solution infeasible (although they might restrict adjacent assignments). If both a NoShift assignment and a Shift assignment overlap for the same employee, the Shift assignment will override the NoShift assignment.

Properties

This component is not nillable.
