At each stage of the recruitment process, you will transition the Position Description / Posting to the next stage. The button Take Action on … has a number of options to choose from.
For example, Reviewers will transition a request for a Position Description to the next stage, or will continue to work on the form, or will move it to the previous step. The order of the approvers depends on each hiring department/college/division’s departmental policies and practices.
Once a position is submitted to the next approver, then the position posting becomes Read Only to the submitter.
