KB279939: Derived metrics in a grid cannot be updated automatically on iPad against MicroStrategy Mobile 10.x

SYMPTOM:
If users configure transaction on a grid and set the control style to some types, such as “Switch” and “Star Rating”, derived metrics in the grid cannot be updated automatically when changing values of the dependent metric(s) on iPad against Strategy Mobile 10.x. The same works fine in Strategy Web.
STEPS TO REPRODUCE:

• Create a report services document with a simple grid.
  
• Created a derived metric using the expression, for instance: Profit + Revenue, and add it to the grid.
  
• Configure transaction on the grid and set the control style to “Switch” for the metrics “Profit” and “Revenue”.
  

• Run the report services document in Presentation mode. The derived metric can be updated automatically when users change the value for Profit and/or Revenue.
  

• Run the report services document on iPad against Strategy 10.2 Mobile. The derived metric is not updated after changing the value of Profit and/or Revenue.
  

• The problem is also reproducible when the control style is set to Star Rating.

CAUSE:
This is a known issue of Strategy Mobile 10.x.
 
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.
 
The Strategy Internal Reference Number for the issue discussed in this technical note is DE26104.
