Has anyone done a Cash Management Cloud implementation for any Irish Banks such as Allied Irish Bank that uses the MT940 Bank statement format? I am facing an issue with AIB where they provide the tag25 (Account Number) field in format CCYSORTCODEACCOUNTNUMBER. Oracle only seems to accept the statement if this field is either the IBAN or the exact account number the bank account is set up in. The bank say they cannot customise this tag25 to provide only the account number. Therefore the statement can be loaded into Cash Management.
