How to flow information from requisition to offer

Summary:

We plan to add a few custom fields to the offer details page (PER_ASG_DFF). We were hoping to add the same set of fields in DFF available in the requisition and then default it on the offer page based on the requisition id. We also want the same information flows downstream to the pending worker stage so that it can be overridden later if needed.

Content (required):

Q. I don't see the requisition id in the derivation field value. Any idea how we can default based on requisition only at the offer stage and then let it flow downstream.
