Display Webdynpro screen on UWL workitem

Hello,

I have created a GP Application in which a user enters information in fields which goes for approval to the approver's UWL....now when he clicks on this workitem i want to display the screen which comes from webdynpro so that I can design it in my own way rather than display fields which come from mapping..one after the other....

Any help would be highly appreciated.

Regards,

Anil
