To change the Ball In Court (BIC) person on a submittal using the project's Submittals tool.
When you first send out a submittal for approval, the members of the first group in a submittal workflow are automatically assigned the 'Ball In Court' responsibility. When all required members of that group submit a response (for example, Approved, Approved as Noted and so on.), the 'Ball In Court' designation proceeds to the next group of approvers in the submittal workflow's sequence. The designation changes in sequential order until all required submitter(s) and approver(s) have submitted their response.
If an approver or submitter in a submittal's workflow needs to change a response that they already sent (or that was input on their behalf), a user with 'Admin' level permissions on the project's Submittals tool needs to first move the Ball In Court back to the approver or submitter.
This moves the BIC assignment to the selected user or group of users and updates their response to 'Pending'.
