Hi Naveen,
This seems to be a complex development. I assume that the fields you want to add here are all display only fields.
You should follow a two step solution:
1. Whichever object (is it ibase?) you are trying to see in component BTREFOBJ, you should open that object in web UI and add a custom field using AET on that object. This will create a DB field on that object.
2. Make this field available in view of component BTREFOBJ.
For this you have two different options, try both
Option1:
a. Use append structure (as you did) to add the field to standard object
b. Enhance GENIL model to read the value of that field from DB table
Option2:
a. Add attribute to context node BTREFOBJ and write code in GETTER method of this new attribute to read the DB value.
