Reject Changes
In case some of the mappings are not acceptable, the reviewer can reject the Mapping Set related changes individually by simply clicking on the needed row in the Review column. This invokes a dialog where the status of that particular mapping can be set to Rejected or Approved.
In case of rejecting or approving items individually, reviewers still need to submit their review. This is indicated by an error message at the top of the editor.
The saving can be performed by clicking on the 
button, by either approving the task changes or sending it back to the author requesting changes. If changes including rejected mappings are approved and then promoted to the MAIN branch, the rejected mappings will not be present among the other approved mappings.
