For all practical purposes, records for any Match-IT file can be imported. The list of files and their fields is available from the on-line help system.
The help topics for a file definition show the field name as tla:Name, followed by a brief description. The tla is the 3 character ID for the file, and the Name is the field name as it should be used in the import system.
LType is the term used to refer to the Match-IT data types that are expected in the import fields. These may be single or multi element text strings. The list of these types and the text elements required is available in the on-line help system.
