Web Service returns empty tables

Former Member — Tue, 05 Aug 2008 11:09:15 GMT

Hi all,

I implemented an RFC FM which selects Business Partners and returns them to the caller. It works fine, but when I published it as a Web Service and generated a proxy no data is returned to the proxy call.

Have you got any ideas what could be the problem? I could not find any notes to this issue.

Best regards

Georg

Hello Georg

You need to distinguish whether the the problem is located on the "Web side" or the R/3 side.

On the R/3 side a potential problem may be authorizations.

For this purpose you should call your fm (via WebService) in a test mode. In the test mode you fill some business partner data yourself to ensure that you have at least some data (no selection of DB tables).

If you can retrieve these data after your WebService call you know that this part is OK but that the problem is on the R/3 side.

Regards

Uwe

Hi Uwe,

Thanks for your instant reply.

No, it is not an authorization problem. It does not make a difference wheter I select some data from the db or I fill an internal table e.g. with two strings. In both cases no data is returned to the caller.

I also debugged the fm (via the web service call) and the tables are filled there, but when I return to my test report, where I call the WS, the table is empty.

I suppose that there is a problem in the Proxy Framework.

Best Regards

Georg
