PO DFF API

Summary

Is there an API available to update PO header/line/schedule level DFF's

Scenario: We're planning on building a PaaS solution to Auto Acknowledge PO's where the due date has been past. However, the client would like to record the method of acknowledgement on either PO header or schedule level DFF attribute for reporting and process improvement purposes.  Our technical team have understood that if the DFF's are updated, this would result in a change order - which is not desirable in this context.

Is there an API/Service already available (that we missed) or one in the pipeline which would allow PO DFF's to be updated without it resulting in a change order.
