How to set logon token timeout in SAP webi 4.1

Hi,

We have intergrated SAP webi report using opendocument url in our asp.net application. We are generating SAP logon token using restful service and appending that token in opendocument url.

But after 4 - 5 mins webi report viewer redirecting us on SAP BI login page. It seems the logon token is getting expired.

So how can we increase logon token timeout in SAP BI.

Thanks,

Ajay
