Hi,
This is hardly PSM-FM related issue and you can, of course, transport FMDERIVE with values. The problem is more related to SAP BASIS, so you'd better check with your BASIS team. Consult note 644610 - Analysis of transport problems - info. for more info.
Regards,
Eli
P.S. Also note 568784 - Termination with client copy (Financials Basis) can be useful.
