Attribute to BOL object relation

Hello All,

Need some help.

I am in process of customizing one of my search result view. I have to add one field to result view. I tried changing configuration but it was not available there. So, I tried creating attribute, here i stuck in finding right BOL entity.

Same field is visible in another view(another component).  i want to see which BOL entity has this field. But i am unable to see this attribute in view context. this field is part of a line item.

Now i have two issues:

1) I am unable to find this attribute in context node. where can i see this attribute in my context node.(it is not in attributes sub menu, it is part of a line         item in table)

2) If i can find this, i want to see from which BOL entity it is being used, so that i can pull the same field in my new view.

can someone help me on this.

Thanks in advance.
