Webi open doc sReportName not working with pdf

Hi,

I have scheduled report as pdf and want to open specified tab, i am using sReportName parameter but its not working. I always get first page of pdf. does sReportName work with pdf format?

I am using following syntax:

https://<server>/OpenDocument/opendoc/openDocument.jsp?iDocID=AUMTO3kNgA9DsMoePZ1Wlgk&sIDType=CUID&sType=wid&sInstance=Last&sReportName=Incident&sRefresh=N&sWindow=Same

Is it possible to navigate through tab when scheduled report in pdf format?

Thanks in Advance

Kumar
