How transitive matching works

Transitive matching uses the following match ID resolution process for each match group on the current rule:

• The system checks if any record in the group already has a match ID from an earlier rule level.

• If a match ID exists, the entire group inherits that earlier match ID.

• If multiple candidates exist, the smallest match ID from the earliest rule level is selected.

• If no prior match exists, the group is assigned a new match ID.
