Why Bank Number and Branch Number is mandatory to be completed when creating Supplier Bank Accounts?

 Hi,

We created a Bank Account for Country = Spain and Currency = EUR

We are completing the following information:

- Bank Name
- Branch Name
- BIC
- IBAN
- Account Number

But the system ask us to also complete BANK NUMBER and BANK BRANCH NUMBER

We believe that this is an issue because it shouldn't be required to complete Bank Number and Branch Number because we believe that is enough with the information that we are completing.

Thanks
