KB249645: The default Percent contribution value in the tooltip of a Pie chart in Visual Insight displays a different value than the derived metric Percent to Grand Total in MicroStrategy Web 9.4.1

SUMMARY:
This Technical Note describes how in Strategy Web 9.4.1, the default value in a Pie Chart, in Visual Insight, for percent contribution, displays a different value than the derived metric, Percent to Grand Total.
 
SYMPTOM:
In Strategy Web 9.4 1, users have the ability to insert a percent to total metric on the fly in Visual Insight. When a user chooses a pie graph as visualization, it automatically gives the user a percent to contribution calculation in a tooltip, when hovering over different slices. If a user inserts a Percent to Grand Total metric, it will display differently than the default percent contribution amount, as shown below:
 

Note how the Percent contribution displays 11.11% and the Percent to Grand Total displays 11.14%.
STEPS TO REPRODUCE:

• Navigate to Strategy Tutorial Project > Shared Reports > Strategy Platform Capabilities > Advanced Reporting Guide, and run the 01 Basic Report. 
• Convert this report into a Visual Insight Dashboard.
• Choose Grid as visualization, then add Region and Revenue to the row and column respectively.
• Add A Percent to Grand Total on the Revenue metric, as shown below.
  

• Change the visualization to the pie chart.
• Hover the mouse over any slice and observe how, in the tooltip, the Percent to Contribution and Percent to grand total do not match.
• Now, increase decimal places for the Percent to grand total metric. See the image below how they still do not match:
  

 
CAUSE:
This is an identified defect in Strategy Web 9.4.1.
 
ACTION:
Currently this issue is still being reviewed for feasibility by our Technology team and it is not scoped for any upcoming scheduled Strategy release.
