To end the employee schedule planning phase, the schedule must be free of working time planning errors. If any errors are present, it will not be possible to end the planning phase, and the system will display an appropriate error message. The planning phase can be ended in two ways:
from the view level

directly from the schedule document.
You must also take into account the date in the PLANNING FINAL END DATE field, as exceeding this date prevents the planning phase from being completed. The exception is the HR department, which can end the planning phase regardless of this date.
