010507: Internal error in distance mapping: <value1>.


Internal errors may be generated if there is a problem using a temp file with a distance operation or if the keyword for the source direction field is not recognized.


If the internal error indicates that there is an unrecognized value in the source direction field, ensure that the direction of travel specified in the field is either FROM_SOURCE or TO_SOURCE.

If the internal error identifies a system temporary file, ensure that there is enough space at the identified location to write intermediate output and that you have permission to write to the necessary location.
