Reference Number to be included in Internal Bank Transfer Payment File

Summary:

Requirement is to capture a bank reference number in payment file

Content (required):

Hi, One of the banks (Banco Industrial) requires an internal Bank reference number to be printed in the Payment file. For the supplier payments, we are using a DFF at the external bank account level and its getting captured in the payment file as well, however for internal bank transfer, this is not possible as the data model is referring to external banks only and not the internal banks. We tried with Account Suffix, Secondary bank Account Reference, Alternate Bank Account Name, IBAN Number fields but none of these values are fetched for internal bank transfer. Could you please suggest
