The system is unable to find or open the location-name.DDT or location-name.DDF files on the path specified. These files contain
essential information on location table and field specifications. Check whether there is a location in the path specified.
Check whether there is more than one set of .DDT or .DDF files in your location directory. Check to see if the location name
matches the location name in the SYSXDB.SYSLOCALS table. Verify whether the path is accessible by the program accessing the
location. For example, in multi-user, use the drive specifier.
