PeopleSoft Approval workflow (Vouchers) suddenly behaves weird

Hi Everyone,

We have faced the issue few times in the PSOFT production instance that the approval workflow especially Voucher approval starts behaving very weird. Even if there are no changes made on approval workflow. It triggers approvals through our scheduled voucher approval submission process but it goes to the wrong approval level and moves directly to final approver saying Error step and skipping rest of approvers in the queue. However if the voucher opens and resubmitted for approval it follows the right path for approval and goes to all approval levels as expected.

The issue remains in the system for new vouchers submitted through voucher approval submission process. We cannot replicate the issue on any of our lower instances, it is working as expected on our Dev and Test instances.
