I used to head up EDI here, and let me tell you, no one, at the time, was
ever a cause for concern. Granted, it's been years.
Mostly EDI goes to an intermediate file. Then your custom programs find a
way to feed it into your system. Your intermediate files could all be
made with max size (or appropriately variable length fields)
RealPO = EDIPO
// truncation exception.
