Model import error - Missing R3NAME or ASHOST in connect_param in RfcOpenEx

[former_member201257]

Hello,

We have a new NWDI setup for our portal development for ESS and MSS components.

(NWDI 7.01 SP 05 and EP 7.01 SP05 and ECC 6.0 )

I am trying to import a WD model (adaptive RFC) into an NWDI project and am getting the following error.

I get this error after searching for the available FMs in the model import wizard, and when I am at the final screen.

However, If I create a local project, I am able to import the model (same FM and same backend system) without any problem.

I guess the problem is with only the NWDI projects and some thing to do with NWDI or SLD connection to the backend system.

The JCo destinations are setup correctly and I have tried using a couple of different logical system names and there is no change.

Does any one have any idea on what I am missing?

Appreciate your response.

Thanks,

Shanti

Here is the error:

Hi,

Can you please check the logon language used during the Reimport Model - in the screen -

"Reimport Model - SAP LogOn Information"

Here the log on data should have the proper language.

Try to access the Back End system and set the user name with the correct logon language in the 'SE01' transaction and give the correct language in the 'Defaults' tab and try to access the RFC from the IDE using the same language.

Regards,

Mohan

Hi Mohan,

I am using language "EN" in the model import wizard and the same has been set as default in my user parameters in the backend system.

I believe the first line of the above error - is just a warning related to the language.

My actual concern is the the second line in the error -

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

Thanks,

Shanti

The problem seems to be more weird.

I can not only import the model in a local project but also import the model in an NWDI project for a different DC.

Somehow the problem is with creating the model in only one of the DCs in the ESS SC.(ess/quotas)

Well, I finally went ahead and finished creating the project (ignoring the error I was getting) and the model works fine after import and deployment.

At this point, I am not sure what the problem was but it does not impact my model at runtime. Every thing works fine as expected.

This seems like a bug ... and the error is somehow showing up unnecessarily ...

Thanks,

Shanti
