Adjusting the Minimum Unique Percentage
You can change the threshold percentage above which a column is considered to contain a unique set of values in the range of 0 to 100. The default value is 90. This setting can affect the Match Percentage Factor when Discovery evaluates relationships. See

1. In Studio, choose Configuration from the Administration menu.
2. Expand the Discovery and then the Relationship branches.
3. Select Minimum Unique Percentage and change the value.
4. Click Apply and then OK to apply your configuration changes.
