Connect to SAP ECC 6.0 database with Crystal Report Viewer for .NET

Hi all,

I want to load a report in the Crystal report viewer which has a datasource connection to a SAP instance.

I can open the report and show my report  in the Crystal Reports 11 application

I can load reports and show results with the reportViewer for .Net for eg.: Oracle databases

Loading my report with an SAP ECC 6.0 database destination also works but after providing parameters and logonInfo I get the error message:

"Error loading the database information" while connection to the SAP ECC 6.0 database

Does Crystal reports viewer works together with SAP ECC? Do I need any additional libraries? Is there somewhere an example code for the connection to ECC databases?

Thanks in advance for your help,

Andreas
