Informatica Data Quality - Match Analysis Ask




In our Duplicate analysis requirement the input data has 1418 records out of which 1380 records are duplicate records.

On using the Match Analysis (used Key Generator, Matcher, Associator, Consolidator) in IDQ integrated with PowerCenter except for 8 records all duplicates were eliminated.

On executing the workflow by excluding these records, duplicates appear in other records for which duplicate didnt occur in the previous run.

Can anyone tell why this mismatch occurs?
