Hi Deb
Any changes in the conversion to words or numbers on cheques needs to take place in X00500 or one of its derivatives (if you use other standard cheque print programs eg R04572U1 for British cheques in boxes). Quite a few JDE users modify this BSFN to suite their local requirements.
I am not quite sure what you mean with the character limit (as I haven't personally changed these Bsfn's), but hopefully this will point you in the right direction.
