3445030 - Web Service: Not Able to Create Purchase Request that Contains Two Line Items via SOAP UI

When creating a purchase request that contains two line items via SOAP UI, an error "RABAX occurred on server side" occurs and no purchase request is created.

But if the payload contains only one line item, or two line items that are exactly the same, purchase requests can be created.
