New PO Suggestion Data to PO Entry

I have some information that is being stored in the SugPoDtl.Character01 field. When I generate a PO from this screen I would like whatever is in the SugPoDtl.Character01 to appear in a PO field so I can use the data on the PO entry form. Would a BPM be my best bet to get this to happen?

Thanks,
Ted
