title: Pentaho Analyzer Report prompt value after refresh
body: <p>I developed a dashboards which have a refresh time of 30 minnutes.
  This dashboard uses a prompt which reads its data from SQL query.</p>
  
  <p>In which way is possible to refresh the dashboard maintaining the last selection in the prompt?</p>
  
  <p>EXAMPLE</p>
  
  <p>Initial prompt value [a,b,c,d] -> Default selected value [a];</p>
  
  <p>A user change the selected to [b,c]</p>
  
  <p>Dashboard refresh</p>
  
  <p>Prompt selection reinitialized with [a];</p>
  
  <p>In which way is possible to maintain the selection after the refresh?</p>
  
  <p>Thanks.</p>
