    it seems that your JCO-Destinations are not defined in a proper way..

    It is important, that you use two JCO-Destinations;

    one for the Dictionary Data and the other one for the Application-Data.

    You have to define two differnt Destinations, one of Type 'Dictionary Meta Data' and one of Type 'Application Meta Data'. Both point to the same R3 System!

    The first one could access the R3 System only via MessageServer, so you have to take care, that accessing the R3-System via MessageServer must work properly.

    Hope this helps, Frank.

      I think I'm stuck up with the same problem. I seem to be creating both types of connections in the SLD. But when I goto Content Administration, it reports an error saying 'No application servers are maintained in the SLD' and same for the message server.

      What am I missing? Please help me !

      Thanks & Regards,

    • Hello Russ,

      let's use the SAP Logon Pad to test if you can make a new Connection using the groups function. First login to your MINIWAS 6.2 and start Transaction SMLG and check that you have a valid Logon-Group. More information could be found in the SAP Help at

      Then open you SAP Logon Pad and click on the button Groups..., enter the Instance name of your MINIWAS 6.2 System in the Field System-ID and enter the Hostname of your MINIWAS 6.2 System in the Field Message-Server. Then click on create list. Now you should see the Logon Group(s) you just have defined. Click on add and try to connect through this new connection.

      If that is working, also your connection through the Webdynpro Content Administrator should work.

    Hello Gregor, thanks for your response.

    As I have posted in another thread....

    My 'services' file has the entry sapmsBSP 3600/tcp with a new line after the entry. I have tried 'PUBLIC' and 'SPACE' both upper and lower and mixed case. Again,

    I go to the SAP Logon pad, click the GROUPS button, enter System ID and message server, then click Generate List, I get a window opening up saying that "Message Server could not find any Groups"

    I see the groups I have created when I return to transaction SMLG, but still can't see them from the stack.

    Any further thoughts?

      Hi Gregor,

      Can you please tell me the configuration for the message server. I have installed Sneak version 6.40 (90 days trial version). I am totally new to SAP.can you please guide me in this situation. SAP R/3 system installed is configured as a single server. I am not able to find the message service sapms<SID> on that system when i am trying to connect.
