FIrst in CMSEL, make sure FACE1 and 2 are scoped to a Mech. face - then include also:
CMSEL,S,FACE1,NODE ! since D command goes on nodes.

SFA is to apply a surface load to an apdl area (this area does not exist in Mech., so we can not use it in MEch, since geometry def., and description is different between apdl and WB/MEch).

You would need to use another command, e.g., check SF command.
Also I would use PRES, with one S in the SF commands

Thanks
