RE-FX Object link is not working

Hi Gurus

I have added the object VICNCN (Screen Number: 500) in DC10 for a document type. Now i can link Real Estate Contract with a DIR in Object Link tab. When i double click the Real Estate Contract number in Object Link tab then the system will open the transaction RECN. So i hope the DIR is attached to that number.

But when go to transaction RECN and select the menu Extras--> Document Management then the system prompts a message to create a New Record. Suppose if click "Yes" then it shows a error "Model Not Found". Actually the Real Contract Number has already been linked in Object Link Tab in CV01N. But it is not working properly.

Can anyone please help me to fix this issue.
