Model node in enhanced UI-Component(BT116QH_SRVQ) not visible under configuration(show available fields)

Hi All,

I have scenario to add model node attribute to the context node BTAdminH of enhanced component( BT116QH_SRVQ) view (BT116H_SRVO/Details) , as I need to show that field in UI screen.

It is a form view.

I have added the attribute to the context node but the newly added attribute is not visible in View configuration in "Show available fields".

Please note that already I gone through SAP note 1575472 and verified and implemented suggested ones but issue is not solved. 

And  also I have gone through some posting regarding Design Layer assignments like "No Design Layer" assignment to the attribute but still the field is not visible in view configuration.

Your help is greatly appreciated.

Regards,

Naresh
