How to restrict employees from adding new goals?

Hi All,

This is a common requirement in most organizations, where they don't want to allow employees to add new goals in the goal plan after few initial months.

For example, if the review period is from January to December, workers should be able to add goals only in the month of January. They should still be able to edit any existing goals throughout the review periods.

However, any new employees who join or become eligible for goal plan during the review period should get one month of time to add their performance goals.

May I know how you are currently dealing with such requirements?
