Running Consistency Checks 
When you run a consistency check, you get a warning message that does not necessarily cause any problem when you execute the rules.
Example
Add condition values in a Decision Table that overlap such as between 15,000 and 20,000, between 17,000 and 25,000. You should see a warning message.
Add condition values in a Decision Table with a missing range such as between 15,000 and 20,000, between 25,000 and 40,000. You should see a warning message.
End of the example.
Procedure
In the Rules Navigator expand the project node and the ruleset or flow ruleset.
In the context menu of a rule in the Rules folder or a decision table in the Decision Tables folder, choose Check Consistency.
Check for message at the bottom of the screen.
