Hi,
I don't think you can generate transports from PRD. I do not know your BASIS's production client backup strategy. If a delta backup copy exists, you can ask them to overlay the old PRD with the delta backup copy. A better way to deal with this kind of need is to use client comparison and adjustment method:
Comparison of Customizing Objects - Customizing (BC-CUS) - SAP Library
There are also other SQL data sync tools; you can google them yourself.
