The Single Source of Truth (SST) record is a view of the most accurate organization information, based on your administrator's setup. Each attribute in the SST record contains either user-entered or source system data, depending on the setup and availability of data. See: Single Source of Truth Overview.
If the SST record is set up, then Oracle Customers Online uses the SST data where applicable, for example, the organization overview and profile.
When you start the process to purchase D&B data for a specific organization, you first view the organization's existing user-entered and D&B information, if any. See: Overview. You can also view that information after purchasing D&B data. See: Viewing Information from Data Sources.
In the Business Verification subtab, you can also compare the D&B data with the Single Source of Truth record, if SST is set up. If not, you see only the D&B and user-entered information in this subtab.
Note: If you have the Oracle Customers Online Superuser responsibility, you can see all three sets of data at the time: user entered, D&B, and SST. If SST is not set up, only user-entered and D&B data are displayed.
