Issue/Introduction

Is there a property or parameter when invoking the sub-report that will say "only print the first page"

Resolution

In Jaspersoft, there is no direct "print only first page" property or parameter for a subreport itself. However, you can achieve this effect by using a printWhenExpression on the subreport element within your main report. 

 

Workaround:

• Locate the Subreport Element:

  In your main report's JRXML, find the <subreport> element that defines where your subreport is placed.
• Add printWhenExpression:

  Within the <reportElement> tag of your subreport, add a <printWhenExpression> tag.
• Use $V{PAGE_NUMBER}:

  Set the expression to check the current page number of the main report. The built-in variable $V{PAGE_NUMBER} provides this value.
