How to Copy/Transfer BPA header DFF value to the PO header DFF

Summary

We have a requirement where the expectation is to copy/transfer the DFF value from the BPA header to the PO header. Both PO and BPA header pages have identically named DFFs, and the PO header should inherit the value from the BPA header.

Kindly suggest if there is a standard approach to achieve this. If not, please advise on any possible extensions or alternatives. Your help would be greatly appreciated.
