MSIR.0397 Invalid (type) change on REDEFINE command of field with SIRFIELD attributes: (field)

This message indicates that a REDEFINE FIELD field command was issued, and that the command could not succeed because field is a SIRFIELD alias or has been specified in a SIRFIELD field FORMAT command. Some forms of REDEFINE command are allowed for fields with SIRFIELD attributes, but this command attempted to change the attribute indicated by type.

See the [[Media:SirfieldNew.pdf Sir2000 Field Migration Facility Reference Manual] for a description of the REDEFINE attributes not allowed after a various SIRFIELD commands. If you wish to make the attempted change to the field definition, you must re-INITIALIZE the file and issue the new DEFINE FIELD command for the field, and re-execute the series of SIRFIELD commands for the file.

The command is rejected.
