3815057 - Why is the report not being reassigned to a batch after successfully creating its Payment Demand ID Manually?

We have encountered an issue with an expense report that was not processed for payment, resulting in the user not receiving their reimbursement. Upon investigation, we discovered that the report had not been assigned to a payment processing batch. We attempted to manually generate a Payment Demand ID; however, despite the system indicating that the manual creation was successful, the report is still not found in any batch.
