KB45342: Smart metric evaluation order changes after re-adding to grid in MicroStrategy Developer

STEPS TO REPRODUCE:
Follow the steps below to reproduce the issue in Tutorial project:

• Create two same Compound Metrics ‘CM1’ and 'CM2' (e.g. metric [Cost] / [Revenue]) with ‘Allow Smart Metric’ enabled.
• Create a report with Category in Row, and metrics CM1 and CM2 in column. Enable Total from Menu -> Data -> Subtotals.
• Go to Menu -> Data -> Report Data Options -> Calculations -> Evaluation Order, and set evaluation order (EO) as shown below:
  

• 
   - EO(Total) = 1
   - EO(CM1) = 2
   - EO(CM2) = 3

  
   
  
  
  
• Remove CM2 from grid in report design view, and find that the evaluation order becomes 'View evaluation order' instead of 'Data Set evaluation order', as shown below:
  

• 
   - EO(Total) = 1
   - EO(CM1) = 2

  
   
  
  
  
• Add CM2 back to grid again, and find that the evaluation order of CM2 changes into Default, as shown below:
  

• 
   - EO(CM2) = Default
   - EO(Total) = 1
   - EO(CM1) = 2

  
   
  
  
  

CAUSE:
This behavior is by design. When the metric CM2 is removed from grid, the report becomes a private base + private subset structure. Therefore, the evaluation order becomes:
For Base:

- EO(CM2) = Default

 - EO(Total) = 1
 - EO(CM1) = 2.

 - EO(CM2) = Default
 - EO(Total) = 1
 - EO(CM1) = 2
