KB404330: "The filter is empty" appears under Report Filter section of cover page generated by print option with MicroStrategy Web

SYMPTOM:
"The filter is empty" appears under the Report Filter section of a cover page when a user selects the Print option for a report which has a filter added by answering prompts in Strategy Web 9.4.x-10.x
 
STEPS TO REPRODUCE:
Execute the following in Strategy Tutorial:

• Create a filter defined with an attribute element prompt.
• Create an object prompt that lists the filter object created at step 1.
  

• Create a report with an attribute in the grid, and the object prompt created in step 2.
• Execute the report.
  

• Go to Home -> Print, and make sure to check "Print cover page with filter details"
• Click on "Show Printable Version" button.
  

• Notice how the "Report Filter: The filter is empty" appears as a result.
  

CAUSE:
The filter is applied as a result of the prompt answer which comes from a filter object that was listed in the Object Prompt.
 
ACTION:
Currently, there is no option to directly show nested prompt answers in the print option or autotext for page header/footer.
 
WORKAROUND:
Create a Report Services Document and use autotext to display prompt answers.  This can be done by following the Technical Notes below:

• KB32345: List of available auto text macros in Report Services Documents
• KB31921: How to make auto text {&PromptN&} display as "Null" in exported PDF when PromptN is optional prompt and no answer is selected in MicroStrategy Developer
