Tracking whether a PO is cancelable (i.e., without penalty) or noncancelable

Hello.  Does Oracle Purchasing provide functionality for tracking whether a PO is cancelable (i.e., without penalty) or noncancelable?  Public companies in the US are required to disclose their noncancelable purchase obligations, and identifying POs that cannot be canceled would be helpful for companies trying to keep track of this amount.  It would also be a helpful budgetary tool to distinguish between expenditures that cannot be avoided and expenditures that could be delayed or canceled if needed.
