Failure in Model Create Step: com.sap.mw.jco.JCO$Exception: Missing R3NAME=

Hi,

I am running NW04sp10 and am trying to connect my WebDynPro to my R/3 backend app server - am running through the FlightChecking example using DevStudio 2.0.10.

Have successfully created my meta + app data JCo's, they test and ping OK from the Content Manager. SLD is fine, connecting happily to the NW and R/3 boxes. One is message server, one central instance.

When the 'create model' wizard tries to build the java proxies though, it comes back with this:

[Fatal]: com.sap.mw.jco.JCO$Exception: Missing R3NAME=... or ASHOST=... in connect_param in RfcOpenEx

Can anyone help?

Cheers guys,

Andy

    Hello Andy,

    Let me see if I understand your question. You are getting an error after filling the parameters in the create model wizard which is even before you search for the Bapis'. If that is correct then <b>I think</b> your problem has to do with your sapmsIDS. double check that your services file contains the systems you are trying to access . you can find the file in this folder c:\windows\system32\drivers\etc . You should have an entry like so <b>sapms<SID> 3600/tcp</b> where sid should be the same as the system name like (IDS or DVH or DVC). This file would have to be updated on the same system as your NetWeaver Developer Studio. I had a similar problem when I started using my laptop for development.

    Hope it helps..

    Thanks,

    Wael
