In order to use a field as a target for a FETCH operation (in fact,
anyplace where a field appears with a colon (:) in an SQL statement)
that field must be defined in the RPG program.

Fields can be defined explicitly by creating a D-spec, or can by defined
implicitly by including them via a file specification or, my favorite,
an externally described data structure.  You say you tried including an
F-spec for SSM01; this should have worked.

If you are still getting an error SQL0312 on the field name, then one of
two things are happening: the F-spec for SSM01 is incorrect or the field
SCCSM is not in SSM01.

If the F-spec is not working properly you should also be seeing an
SQL1001 earlier in the precompiler error list telling you it could not
open SSM01.  Otherwise, the field is not in the file.  Do a DSPFFD SSM01
from the exact same place you are doing the compile and make sure the
field named SCSNM is in the file.
