Hi David,

Thank you for put this tutorial available on the net;-)

I have been trying to use webservice as data source for CrystalReports XI. I am able to go all the way till have it displayed as a database field and am able to see all the fields listed and drag-drag to my report template design view. But failed to preview it. I get this error:
———8<———
Cannot determine the queries necessary to get data for this report.
Details: Cannot access web service
———8<———

Could you please advise what might be the problem?

ps. I'm not able to connect to the http://www.ecubicle.net/driving.asmx, although I have no problem retrive the WSDL file from my browser.

Thanks in advance

Okay Suma thanks for the suggestion. I can definitely do that. We can connect to Web Services via a Universe as well. For BusinessObjects XIr2, we created a new extension to the Universe called a "data feed as a universe". There are more details here: https://www.sdn.sap.com/irj/boc/innovation-center?rid=/webcontent/uuid/50c178ec-15f2-2b10-65be-85fd40d6c001 Now that we have Data Federator, you can also use that to connect to a web service. Then the Universe can talk to Data Federator via the JDBC/ODBC bridge.

David, Thanks for this walkthru. I get all the way through the steps but in the last step to view the report I get an error:

Cannot determine the queries necessary to get data for this report. Details: Cannot access web service. System.WebServices.Protocols.SoapException: Server was unable to process request, —> System.NullReferenceException: Object reference nto set to an instance of an object….(theres more.)

Any Ideas?
