You should be able to do this using the current(date) function in query :-
TD char(current(date) + 1 DAYS)
/* this will give you tomorrow’s date in date format (with separators) */
TOMDAT SUBSTR(YD, 1, 2) ||
SUBSTR(YD, 4, 2) ||
SUBSTR(YD, 7, 2)
/* Substring and concatenate the date value, without separators */
You may have to change the substrings, depending on your date formats.
(also in netherlands).
