Dear all,

My WebDynpro UI work successfully.

<b>Cause</b>

imported AIN using SAINT but forgot import AIN component using SPAM

<b>Solution</b>

Import AIN component at spam and choose Message server which import the component in 'Maintain JCo connection'.

Thank you for all help.

Hi,

For my knowledge user should have special profiles on the backend system for accessing the DDIC types.

Dear Pran,

How can i check in the backend which i am trying to call has the required function modules? What's transaction?

Hi Nutida,

You can look at function module through transaction SE37.

If you don't knoe the function module then check what is the name of your model node. your function module name would be same as your model node name.

hi,

Usually this error comes when sld is not configured correctly or the JCO connections are not set correctly.Please verify it once more.At runtime the application is trying to fetch the dictionary types for the model metadata .But it is not able to do so .That is why you are getting this error.If this wont work then reimport the model once more

Dear all,

I have already tested JCo connection follow as both suggestions and found that its connection successful. I wonder <b>this error can occur by only improper JCo connection,Right?</b>

<b>Or,Are there any cause to make this error occur?</b>

Thank you,

Hi Nutida

Hi Nutida,

After importing model for your RFC have you re-imported anymore?

If yes then restart your J2EE engine once then check it out again.

Hi Nutida

If you are creating or changing code(doing import) consider doing to another name space , I see sap.com in the URL. My assumption was this was standard SAP delivered code. This however is not related to the current problem.

Hi Nutida,

Check your JCO connections are working properly or not.

For that go to http://<Auto-id's IP>:50000/webdynpro/welcome

there, click on content administrator.

here you can find your JCO connections by clicking on Maintain JCO connections.

Test your JCO connections here.

Go to Content Administrator, check if the JCO Connections are proper.
