Duplicate Record Exception Mapping

Duplicate Record Exception Mapping

Configure a Duplicate Record Exception mapping that examines customer records and finds duplicate records.
The following figure shows the Duplicate Record Exception mapping:
The figure shows the Customer_Details object linked to the mat_MatchData transformation. The mat_MatchData transformation is linked to the exc_Consolidate transformation. The exc_Consolidate transformation is linked to the Write_GoodMatches_Customer target and the target_CustomerConsolidate target.
The mapping contains the following objects:
Customer_Details
The data source that might contain duplicate records.
mat_MatchData
A Match transformation that examines the customer data to determine if records match. The Match transformation creates a numeric score that represents the degree of similarity between two column values. An algorithm calculates a match score as a decimal value in the range 0 through 1. An algorithm assigns a score of one when two column values are identical.
exc_Consolidate
A Duplicate Record Exception transformation that determines which records are possible duplicate customers, known duplicate customers, or unique customer records.
Write_GoodMatches_Customer table
Table that receives all the records that do not need manual review. The Duplicate Record Exception transformation writes duplicate records and unique records to this table.
Target_CustomerConsolidate table
The Exception transformation writes the possible duplicate records to the Target_CustomerConsolidate table. Records in this table require manual review in the Analyst tool.
