What is the expected behavior when a batch Approver is also a Requester?

Provided 'Split Batch' feature is enabled at the Threshold Maintenance ID window, the payment(s) that fall within the given Approver's level will be auto-approved. The higher level payment(s) will be submitted to the other Approver(s) in the higher level range.  Without 'Split Batch' marked, the payment batch will only be submitted for the higher level threshold group.

NOTE: If it is the case that you only have one Threshold range and your Approvers are also Requesters and it is your business rule to exclude Auto-Approvals from taking place meaning the Approver cannot Approve any payment if he/she was the Requester for that payment, this is only supported in Mekorma Legacy User-Based Security.
