Microsoft InfoPath form generation cannot be completed for this external content type because it contains complex data types which cannot be rendered automatically. An empty InfoPath form was generated. Go to the external list {0} and click on Design Forms in InfoPath to create the layout. You may disable offline sync for external lists in the Summary View of this external content type until the InfoPath form has been customized, because the form will not be usable in SharePoint Workspace. This setting will not disable offline support for existing external lists based on this external content type.
