To define Single Source of Truth display and source system overwrite rules:
View attributes for the entity you want to work on.
Select the attributes to update display rules for.
You can define the same rule for all or some attributes, or use a different rule for every attribute.
Select the SST display method.
Select data sources. See: Selecting Data Sources.
For the Rank display method, also define the source system overwrite rule. See: Overwrite Rules for Attributes with Rank Method.
Run the Third Party Data Integration Update program. See: Third Party Data Integration Update Program.
Note: Multiple attributes separated by slashes belong to the same attribute group. The same display and source system overwrite rules apply to all attributes in the group. See: Attribute Groups.
Select data sources for either the Rank or Date display method.
Note: For both methods, the User Entered data source must always be selected for SST.
For the Rank method, you must also rank the selected sources.
For the data source ranking, only sources in the Ranked Data Sources box are considered for the Single Source of Truth record, with the uppermost as the highest ranked.
The ranking not only determines the SST attribute values, but also:
Which source systems can potentially overwrite user-entered data in the SST record. For the selected attributes, you can define the source system overwrite rule only with systems ranked higher than User Entered.
The overwrite rule between source systems for the selected attributes. For example, for D-U-N-S Number, D&B is ranked above the Gorman legacy system, and the SST record currently has a D-U-N-S Number from Gorman. If you later acquire a D-U-N-S Number from D&B for this party, then the D&B value overwrites the Gorman value in SST because D&B is ranked higher.
