use of application and country in BTE implementation

Hi all

I am trying to implement a BTE 2040 in my system.

The issue is it is already been implemented with application as FI-FI in fibf.

But because of that it never gets executed

i refered a note which says to implement BTE 2040 country and application must be blank.

To proceed further i need to understand the role of both these fields in BTE .

Can anyone explain me the same. Thanks in advance.
