Full Supplier's Bank account number

Hi,

We have a requirement to map Suppliers Bank account details and as part of it need to extract and map the Supplier's full bank account number. But, we are getting only the last four digits of the Bank account number as these are masked.

We are aware of that, if we unmask the Bank account number from System Security Options, then the full bank account number will be extracted and this leads to serious audit issue.

Hence, can you please suggest us is there any way to extract the full Supplier bank account number without unmasking from System Security options.
