    Rules and definition

    AOS2 (additional optional service) is an optional extension to EPC's rules regarding the usage of Remittance Information, increasing the maximum number of Strd elements from 1 to 999 and the allowed size of the element from 140 to 280. However, only Finnish banks are able to accept AOS2 structured messages.

    Without AOS2, due to Strd's size restriction, transaction block has room to transfer only reference number. With AOS2, it's possible to send multiple invoices and credit notes along with the reference number.

    FA has a set of rules regarding correct usage of AOS2. The rules are shown in this graphic table:
