Suppliers Using a Bank Account

Hello all, this is, I am sure simple but it is driving me mad...

I am Ok with creating a new bank account and allocating it to a Supplier via the Supplier web page.

However, I would like to do a query based on combinations of Branch Name, Bank Number, Branch Number & Account Number to look for suppliers using specific Bank Account.

Surely, you must be able to do this! Certain you could in R11 but can't work how to do it in R12.

I would have guessed you could do it by Setup/Payment/Bank Accounts but when I do this, I can only see 'Internal Bank Accounts'
