3176092 - How does the ERPAllowCancel flag influence order cancelation within Ariba?

Why is the system not allowing the POs within P2P to be canceled? The error Purchase order cannot be canceled comes up when we try to initiate a cancellation. When changes are made to the split field, the error Submit will cancel the existing requisition PO XXXX number. This is not allowed.
