Question -------- Should the year on the ISA date value on a version 4.10 (and above) transaction set reflect century (e.g. 1998 or 98)? If yes, this would make the date 8 digits. Answer ------ According to the EDI Institute, the date on the ISA is an envelope time stamp; they do not foresee making the ISA year on that date reflect the century in the near future.
