How to default PO header DFF from PO Total Amount

Summary:

Hi,

I am looking to default a PO header DFF with the PO Total Amount at the moment of the creation of the document. We want to stor the purchase order original amount to be able to use it in approval rules.

Has anyone been able to do this? Using SQL for example?

Thank you,

Eolie
