Hi,

    I did JCO Metadata Dest for the R3Enterprise. I think it is common for all the SAP systems.

    What you should do is, just go to Content Admin->WebDynpo's and Open your Application.

    Create Metadata JCO Destination for getting the metadata information for the BAPI or RFM.

    Steps to follow.

    1) General Data: Provide your Meta Data Dest name and client number.

    2) Just Press Next

    3) Select Dictonary Meta Data and Press Next

    4) Select your Message Server and Select your Logon Group PUBLIC and press next

    ( Note: you must have valid configuration for your messaging server and Logon Group ( some times it SPACE ) in WAS SLD )

    5) Enter your uid and password and next and Finish.

      I just looked at the previous posts at

      problem-testing-metadata-in-jco-connections-flight

      It looks like this kind of problem is common with miniSAP users.

      There are some tips like setting up sld using RZ70 which you may want to try

      The following point might be helpful

      Thanks for your follow-up. ST22 and SM21 did'nt point to anything. What is realy interesting is when I go into SMLG, create a group, use RZ70 to push the changes out, then go into .../Webdynpro/welcome...and run the wizard to create the RFC_METADATA, the group I just created in SMLG is displayed in the Group dropdown.

    Hi Hans

    Have you checked if you have maintained the JCO destinations properly for your Web Dynpro App. This is available through the Web Dynpro Content Administrator

    http://<server>:50000/webdynpro/welcome/

    Regards

    Pran

      Hello,

      thanks for the tips...i think that is where the problem is, i didn't set up a message server connection for the metadata retrieval since this did not work.

      Has anybody ever set up a message server connection to Mini SAP WebAS 6.2? I don't even get a ping although i already created a logon group PUBLIC and checked that the service entry is correct (port 3600). Any ideas on that one?

      Thx!
