Salesforce Duplicate Management App – Unique Identifier.
For Unique Identifier, a user can select a combination of 1 to 3 fields.
For example, a user might select a Lead object and configure a combination of First Name + Last Name + Email. This combination is the unique identifier. Thus, the app considers all records that match the value of “First Name + Last Name + Email” as duplicates and they will be offered for merging.
After the unique identifier is selected, the app will show the user a list of suggested master records. Additionally, a list of records for each Master record will be displayed. If the records have different values in the matching fields, our Dedupe Application will then offer to choose the correct value for each field. If there are no discrepancies, the app will offer to merge records.
After merging records, the Duplicate Management tool redirects the user to a newly created record. This record contains downloadable reports, including a Salesforce duplicate management report.
