How can I add roles as approvers or reviewers while approvals are in progress?

In the Search and Select: Users and Roles dialog box, you’ve two options: Person or Roles. After you select the participant, the Add Participant page is displayed.

In this page, you can do the following:

• Change Activity Type to either Approval or Review.
• Change Response Required From to One or All.
• Add comments. These comments appear in the notifications sent to the new approvers or reviewers.

Note:

• You can only remove individual users if the user is part of a role and the response required from that role is set to All.
• You can't add Activity Type = Optional approval when the approval is in progress. This is the existing behavior.
• You can't send different comments to approvers and reviewers in a single Submit action.
• When the change assignee is modified, the new assignee:
  • won't receive the notification that the workflow is complete.
  • can't perform BPM worklist actions such as reassignment on the current approval notifications.
