To send back the task to the author in order to request changes, the reviewer should click on the button and select the Request Changes option. Adding comments is also possible.
A mapping that has been rejected and sent back to the author, won't affect the actual Mapping Set. Requested changes still need to be made and sent back to approval, in order for a reviewer to be able to promote the changes to the MAIN branch. As long as no promotion has been done, the rejections and/or approvals won't affect the actual Mapping Sets.
Apart from the above described, all functions work according to the traditional workflow.
