John Lanoue receives a remittance advice (ASC X12 820) from a company
through a bank. But in ISA04 (Security Information) the security code
is different every time there is a new transmission.
Dear John:
What does ISA03, D.E. I03 (Security Information Qualifier), contain? If
it's "00", it means there's no Security Information Present and that
there's no meaningful information in ISA04 - the field may as well be
ignored (though it's usually all blanks in that case).
The bank generally provides its own ISA, though it could be simply
copying the ISA03 and ISA04 provided on the ISA as it forwards the
remittance advice from your trading partner. Only if the bank is
preserving the originator's ISA (unlikely - though who's the sender on
the ISA you received?) could you lay the blame on your trading partner.
I really never understood the purpose of the ISA's security
information - the ISA is neither encrypted or autheticated even if the
X12.58 security standards are used. I doubt a crummy little password in
ISA04 is all VANs or banks rely on for security for financial
transactions!
So why not just ignore the ISA04?
