Hi Bhavik,

As per ur instruction,In Webdynpro content administrator,Check SLD connection->Test connection if i test,it displays

Connection to System Landscape Directory was successfully tested.

In visual amin->CIM CLIENT GENERATION SETTINGS->CIM CLIENT TEST,it displays

CIMOMClient Object generation and connection test successful.

in webdynpro content administrator->deployed content,i am able to open all other webdyn pro application apart from the webdynpro application by using adaptive RFC model.

if i open the webdynpro application by using adaptive RFC model,then only i am facing this error.

pls let me know how to solve the error?

regards ,

Hi Raja,

In webdynpro content administrator, you will have maintain JCO connection button. There you can find your JCO connections name which you have specified in your webdynpro application at the time of creating RFC model.

Here, you will find option for creating this JCO connection. Provide your R/3 system details here.

And then test your JCO connection.

Regards,

Bhavik

Hi Bhavik,

Thanks

Hi Raja,

Let me know following things:

1. Have you specified SLD connections?

In Webdynpro content administrator, you will have one button for test SLD Connection. Using this test your SLD Connection. If your SLD is not started then use another button to start the SLD and then test the SLD connection.

If SLD is not configured, you have to configure this setting in visual administrator.

Open go.bat available at usr\sap\<SID>\JC<system number>\j2ee\admin.

In this, select SLD data supplier service unsed server->services.

In this, Provide SLD information in tab- CIM client generation settings.

Bhavik

Hi Raja,

You have not configured JCO connections for this in Webdynpro content administrator.

Goto the URL:

http://[host]:[port]/webdynpro/dispatcher/sap.com/tc_wdtools/Explorer

Here, Create JCO connections which you have specified at the time of creating RFC model in webdynpro application.

Regards,

Bhavik
