BAI no longer maintains the BAI2 standard. BAI2 has become BTRS (Balance and Transaction Reporting Standard), under the auspices of X9, the accredited standards group. BTRS is ANSI approved and is being adopted globally, and it is backward compatible with BAI2. Here is the link to X9 https://www.x9.org/home. At X9, search on "BTRS" and you will find the new standard with instructions on how to obtain it.
