SYMPTOM:
Duplicated records are seen for same data after running an Incremental Refresh Report to update an intelligent cube in Strategy Intelligence Server 9.x.
STEPS TO REPRODUCE:


Sql
UPDATE test SET Location_Level = 1 WHERE Year = 2009 AND Boutique ='B';

CAUSE:
This is an expected behavior. For any change for any other attribute, a new line is added and the previous line also persists.
For examples of how each refresh type option of an Incremental Refresh report works, refer to the following Strategy Knowledge Base article:
KB45837 - How the Incremental Refresh option works in Strategy 9.4.x?
ACTION:
Contact Strategy Technical Support for an updates of this issue.
WORKAROUND:
If user wants to see the updated record only, republish the intelligent cube directly. After the intelligent cube is republished, now the report shows only the updated record, as following:
