A process submitter has the ability to Reset or Edit a process Process even after it has been submitted to reviewers if the Reset/Edit Process setting is enabled in the Admin console.
If you are a reviewer and have made an Approve or Reject decision by mistake, you can ask the process submitter to simply Reprocess the process and you can make a decision again.
1. Click Reprocess button directly from the post view or Click Reprocess in the process pop-up screen
2. Edit the process setup and make comments (optional)
3. Click Start Process
