The Background
By default the Pentaho BI server is configured to auto submit the parameters when running reports. This means that each time the user selects a parameter value the report is being reloaded to reflect the results for the current selection.
This behaviour might not be desirable especially if there are many parameters and the report takes some time to be generated. It might be more user friendly to enable the users first select all parameters and then load the reprot by clicking 'view report'.
Instructions
To disable auto-commit the users can unclick the 'auto-submit' on each report.
To set the default value of auto-commit to 'false' edit the file pentaho-solutions/system/reporting/plugin.xml to set autoSubmit=false
<operation>
<id>RUN</id>
<command>content/reporting/reportviewer/report.html?autoSubmit=false&solution={solution}&path={path}&name={name}&locale={locale}</command>
</operation>
