Design Studio - BW Datasource - Connection Failure

Dears,

I recently updated our BI Platfomr to BI 4.0 SP7 in oder to connect our Design Studio to our BW 7.01 SP 7.

While launching Design Studio, i connect sucessfull to our BI Platform. But if i want to add a DataSource from our BW system an error occurs.

btw. for the other BI Client tools the connection to the BW system works fine.

I attached the error message.

Many thanks for your support.

Regards,

Felix
