How to designate Overriding Approver by Oracle Visual Builder Add-In for Excel

Summary:

I'd like to enter Overriding Approver by Oracle Visual Builder Add-In for Excel when uploading a purchase requisition.

I found 3 fields to designate an overriding approver as follows:

• Overriding Approver Id
• Overriding Approver
• Overriding Approver Email

However, I could only use "Overriding Approver Id" to register overriding approver, and couldn't use other 2 fields because it ended in error.

How can I use "Overriding Approver" or "Overriding Approver Email" fields? Is there any required setups to use these fields?
