The potential duplicate generator reads from the SBR bucket files created by the master index generator and generates any potential duplicate linkages. The potential duplicate generator creates block buckets from the SBR records and matches the SBRs of each record. If two records have a matching weight that is above the duplicate threshold but below the match threshold, they are added to the potential duplicate table in the master index image files. This table is loaded directly into the master index sbyn_potentialduplicates table. Once the Bulk Matcher completes this phase, match processing is complete.
