If there are multiple self reviews submitted to the manager at the same time, the manager will need to complete all the reviews that have been submitted before submitting the reviews to HR. If the manager only completes one of the reviews and clicks on the "Submit Reviews to HR", all the reviews (the one review completed and the incomplete reviews) will be sent to HR.
For example:
There were two (2) self reviews submitted to the manager.
The manager completed one (1) review.
Manager clicks on the "Submit Reviews to HR". As a result, both reviews (complete and incomplete) are sent to HR. The manager will not be able to edit and complete the incomplete review. The manager will need to contact his or her company Admin to have the incomplete review sent back.
