Updating an existing field mapping

To update an existing Field Mapping, simply select the row in the Field Mappings List, then either change the mapping definition in the window below, OR select a new mapping type and enter the details as if you were creating a new field mapping from scratch.  In this case a warning is displayed to indicate that the previous mapping information will be lost.

After entering the new values click on the Apply button.  Note that the format of the field mapping details presented will depend on the field mapping type (Simple, Assignment, Value Match, Reference, Lookup, ID List or ID Replacement).
