KB442378: Running a report using MicroStrategy Data Connectors or REST API returns fewer rows than in MicroStrategy Web and Developer 10.x and 11.0

SUMMARY
Users hit a row limit of 400000 rows for projects created pre Strategy 10.2 and a row limit of 1 million rows for projects created post Strategy 10.2. This affects Data Connectors and REST API.  
 
STEPS TO REPRODUCE

1. Using Rest API, call a Strategy report with 1 column using the Post /reports/{reportID}/instances call
2. Check the response body for “Current”
3. Only 400,000 or 1,000,000 rows appear for “Current”

CAUSE
There is a governing setting that is not exposed in the GUI. For projects created pre Strategy 10.2 limit is 400,000. In other words, Rows x Columns will not exceed 400,000. 
For projects created post Strategy 10.2, the setting for maximum number of nodes for visualizations is set to 1 million. This setting cannot be changed out of the box.
WORKAROUNDS
*NOTE: THE WORKAROUNDS MAY CAUSE PERFORMANCE ISSUES DUE TO INCREASED AMOUNT OF DATA BEING RETURNED. THIS WILL ALSO AFFECT 
1. In Strategy 10.11, 11.0, 10.4.6, 10.4.7, and 10.4.8, a setting called “maximum number of nodes for visualizations” can be exposed and changed in Strategy Developer by adding a registry key setting. Once this registry key is added, the setting for “maximum number of nodes for visualizations” will be exposed in Strategy Developer.
Instructions on how to add the registry key:
 

• Create a new string key "EnableMaxDataCellsForWindows" in registry 32-bit Windows: \HKEY_LOCAL_MACHINE\SOFTWARE\MicroStrategy\DSS Agent\ 64-bit Windows: \HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MicroStrategy\DSS Agent\
• Set the EnableMaxDataCellsForWindows value to 0 or leave it empty, the Maximum number of nodes for visualizations setting will not display in Developer.
• Set the EnableMaxDataCellsForWindows to 1, go to Developer --> project configuration --> Governing Rules --> Default --> Result sets page,  'Maximum number of nodes for visualizations' setting will display. The value range is 0 ~ 2147483647. The default value is 1000000.

If using Strategy 10.10:

1.  Install Strategy Developer only from any of the above versions(10.11, 11.0, 10.4.6, 10.4.7, or 10.4.8).
2. Create a project source in Strategy Developer
3. Connect the newly created project source to the 10.10 server
4. Navigate to project configuration>Governing Rules>Default>Result sets
5. The setting should appear at the bottom of the list  

*Note: you can have a higher version Intelligence server pointed to a lower version of Developer (e.g 10.4.7 Developer machine pointing to a 10.10 I-server.)
 
2. Using the Intelligence Server SDK you can modify the Maximum number of nodes for visualizations. See the following KB article explaining this method:

ADDITIONAL INFORMATION:
 
The Strategy SDK allows you to customize the standard Strategy Web interface, and extend and integrate the Strategy business intelligence functionality into other applications. However, before changing the way Strategy Web products look or behave, it is helpful to understand how the application is built.
