Export To PDF

Hi,

I am creating a VC report from BI query. In that I want the data to be send to PDF. For that I am using Web Analyzer API. But when I click on Export to PDF button it gives a runtime error

<b><b> An exception occurred while processing a request for :</b>iView : pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.ip.bi/iViews/com.sap.ip.bi.bex

Component Name : com.sap.portal.appintegrator.sap.BWReport

Exception in SAP Application Integrator occured: Invalid node mode 'preview'..</b></b>

I am using VC 7.0 Netweaver 2004s SPS10.

cheers

Jayant
