DIC2641 NO GENERATION LOG ENTRY FOUND

UNIX Predict version 4.1.2
I incorporated a DDM into Predict - the file is in Predict, but the pointer to the DDM looks strange - file number 0. I tried to disconnect or purge the DDM but I get a DIC2641. If I generate the DDM I get another entry pointing to the file number.

Plan 0 - Select Implemented File -

Cmd from File M Mem/DBnr Lib/Fnr External object

__ EXC-PARCEL Y 0 0

Is there any way I can get rid of this entry?

Thanks
