You've probably checked but is there a blank or extra underscore by any chance?

Subject: Error creating DSPF
Has anyone seen this issue before?:
A WSSGL_DESCR B 12 93REFFLD(SGL_DT_DES)
CPD7616: Keyword ignored because of error in list of values.
CPD7534: Length of keyword value not valid
If I replace one of the underline characters in the REFFLD name then the error goes away (but, of course, I get a Field not found error instead).
