vendor payment issue

I am getting a warning while trying to do vendor payment . 

"Neither the IBAN nor the domestic bank account number is available for the bank account  for vendor V000005. Please select Setup > Bank accounts, and then add the IBAN and/or the domestic bank account number on the General tab for the specified vendor".

I followed the steps of bank setup as suggested here but still the issue is not resolved ...

Please help me on this..
