Business Area is not getting updated in "Main Bank Account" Line item (FF_5

Hi Gurus,

I am executing T Code: FF_5 for uploading the "Multi-Cash" Format. This transaction clears the Bank Clearing Account and post the entry to the credit of "Bank Main Account".

Now while i had executed F110, the Business area was properly captured in the Bank Clearing Account Line item. But while executing FF_5, the Business Area is not getting captured against the "Main Bank Account" Line item.

Can you please tell me how to capture the Business Area against the "Main Bank Account" Line item.

Rgds,

Prasad.
