Selecting this option will match records exclusively from a secondary dataset—such as an imported enrichment file—against a designated Master Table, rather than conducting a full match across all data.


It’s best suited when the Master Table is a clean, trusted source that has already been deduplicated or validated. 


To preserve data integrity, the system also performs a quick internal scan for exact matches of the Master Table to flag any high-confidence duplicates on the All matches tab for potential review


By using this approach, users can streamline the matching process, minimize unnecessary processing, and confidently identify relevant matches from new or external sources


Click the "Match Against Trusted Source" option and then select the Master table from the drop-down.
