You can configure a source system as distinct so that records from the source system don't match each other but match records from other source systems. Distinct source systems help reduce unwanted matching of records.
If most of the records in a source system are unique, you can configure the source system as distinct to avoid matching of records within the source system. For example, the Dun & Bradstreet database provides unique data. To avoid matching of these records, you can configure the Dun & Bradstreet database as distinct.
However, you can allow records from a distinct source system to match each other by the declarative rules that identify record pairs for manual merge. The users can manually review these record pairs.
For example, consider a match model with two declarative rules, Rule 1 and Rule 2. The merge strategy of Rule 1 is set to manual, and the merge strategy of Rule 2 is set to automated. Set the HR source system as distinct. In this case, Rule 1 and Rule 2 don't match the records that belong to the HR source system.
If you allow records from the HR source system to match each other by the declarative rules that identify record pairs for manual merge, Rule 1 matches records that belong to the HR source system. The identified record pairs are sent for manual review.
Configuring a distinct source system
You can configure a source system as distinct so that the records that belong to this source system don't match each other.
1Open a business entity, and click the Match tab.
The list of match models appears.
2Click Source System Settings.
The Source System Settings page appears with a list of source systems.
3Select Distinct for All Merge Strategies for the source systems that you want to configure as distinct.
The source systems become distinct and doesn't match the records with any declarative rules.
4To allow records from a distinct source system to match each other by the declarative rules that identify record pairs for manual merge, select Exclude Manual Merge Strategy.
