internal/external matchup

External matchup is defined as the C# assembly configured in the configuration table. Internal matchup is defined as the internal import matchup logic as documented in the business logic manual. If the external matchup is to be used with the <import> command, the use_configured_matchup='true' attribute has to be specified (as the <matchup> command is intended to be used for exactly this purpose, it is implied there and cannot be set/unset). The internal matchup can be forced with both commands by using the force_internal_matchup='true' attribute.

The internal/external matchup can be disabled by setting matchup=’false’ on the <import> command.

Note: CRM.interface is capable of three different matchup types.
