Using the field values read from the import file, and the field mappings, update the database. Field paths can be specified as unique so that rather then creating a new target, the database is searched to find an object that matches the specified value. If none is found in this case then a new target is created.

mds - the mutable data source

pathList -

fieldMaps -

fieldValues -

vl -

Throws:

java.lang.Exception - a serious problem
