The option  Is Lock locks the individual frequency of review

The option Enable auto lock based on end date automatically locks the individual frequency of review on the end date

The option Lock Review Period locks the display of set goals and competencies associated with the review period.

It is advisable to keep the review period unlocked during creation to allow necessary updates. Locking should only be considered in rare cases where no further changes are expected.
