[Former Member]

Hi all,

Here i am developing an application which uses adptive RFC methodology in which i am calling an rfc which retrieves simply table data. When i click on the button it should call a RFC internally get the data from the table but instead it is giving an exception i.e.

Could not create JCOClientConnection for logical System: WD_MODELDATA_DEST - Model: class gmr.Model. Please assure that you have configured the RFC connections and/or logical system name properly for this model!

In the above WD_MODELDATA_DEST is my model data destination.Please suggest us how can i overcome this issue.

Note:- When i test the JCO from Webdynpro content administration that is successfully pinging.

Hi Suman,

I am facing the same problem. Could you let me know the process of resolving this issue.

What do you mean by adding authentication to the application?

I would appreciate your help.

Hi Bala,

My model name is "Model " if you resolved the same issue by disconnecting JCOs Please can you send the code accordingly ? as we have many sublinks inside it.

Model model = (Model) WDModelFactory.getModelInstance(Model.class);

if(model!=null)

model.disconnectIfAlive();

Dear Bala,

I am facing the same issue after adding the piece of code which you have sent to me. I added the code after callin the component controller method which internally calls Model object. Please do the needful.

Some times it is working and some times it is not working. is any chance that the problem with RFC or the BASIS have to do some config settings or we need to add any other code. Please do the needful.

Regards,

Suman

Suman,

are you using the same jco.if not check the properties for different jcos in webdynpro content administrator.

I guess there will be some difference because it cannot work in some places and work in some other places
