Launch Safari in Mobile BI app from a Design Studio application

Hi,

We have a business use case for a Design Studio application where the users need to open a document, e.g. PDF, stored on the corporate intranet built in MS Sharepoint. When a user clicks on row in a crosstab, this script is executed (URL is just an example):

      APPLICATION.openNewWindow("http://intranetURL.net/page/page/document.PDF")

This works fine in BI Launch Pad on desktop, and a new tab of Internet Explorer opens with the document. However, when users run the applicatoin on an iPad from SAP BI app, an  they get the error "The operation couldn't be completed. (NSURLErrorDomain error - 1012.).

For some reason, the built-in browser in SAP BI app cannot recognize and open the corporate intranet URL, but easily opens any other world-wide-web URL, e.g. http://www.google.com

Does anyone know how you can launch Safari on iPad from a DS application instead of using the in-app browser? Opening intranet pages from Safari directly works perfectly.

Any help will be much appreciated!
