We had users report this same problem against our VMS client (ABC).
While investigating, one of our customers sent along this extract from one
of IBM's problem managment systems.  Here is that info:

     PQ28166 ADSM CLIENT RESTORE/RETRIEVE FAILS W/ ANS4032E ON DATA THAT
     WAS  EXPORTED FROM ONE V3 SERVER & IMPORTED TO SAME OR ANOTHER SERVER

      ADSM development has uncovered a problem with the restore and/or
      retrieve of data that has been exported from one ADSM V3 server and
      imported on the same server or on another server. The actual
      export/import process works just fine. The problem does not appear
      until the client attemptsto restore or retrieve this data.  One
      reported symptom on theclient is an ANS4032E Error processing 'file':
      file is not compressed. Another symptom is that the client will
      reportreturn code (RC) 150, which means "unknown file/data type
      during restore or retrieve".
