I am trying to subtract 30 minutes for the system time

-SET &D_ST_DATE = &YYMD;
-SET &D_ST_TIME = EDIT(HHMMSS('A8'),'99$99$99');
-SET &DT_TIME = EDIT(&D_ST_DATE, '9999/99/99') |''| EDIT(&D_ST_TIME, '99:99:99');
-*-SET &DT_TIME1 = HADD(&DT_TIME,'MINUTE',-30,8, &DT_TIME1);
-SET &DT_TIME1 = HADD(&DT_TIME, 'MINUTE',-30, 8, &DT_TIME1);

not sure what I am doing wrong

Unfortunately, when using Date-Time functions in Dialogue manager, you have to first convert the DM variable to a Date-Time field, as in this example:

-*-- Date/Time using Dialogue Manager --------------------------------------------

-SET &ECHO=ALL;

SET HOLDLIST   = PRINTONLY
SET HOLDFORMAT = ALPHA
-RUN

-SET &CUR_DATE = &YYMD;
-SET &CUR_TIME = EDIT(HHMMSS('A8'),'99$99$99');

-SET &CUR_DTTM = &CUR_DATE | &CUR_TIME;

-*-- Syntax --------------------------------------------------
-*-- HINPUT(inputlength, 'inputstring', length, outfield)
-*-- HADD(value, 'component', increment, length, outfield)
-*-- HCNVRT(value, '(fmt)', length, outfield)

-SET &NEW_DTTM = HCNVRT(HADD(HINPUT(14, '&CUR_DTTM.EVAL' , 14, 'HYYMDS'), 'MINUTE', -30, 8, 'HYYMDS'), '(HYYMDS)', 20, 'A20');

-SET &NEW_DTTM1 = EDIT(&NEW_DTTM, '9999$99$99$99$99$99');

-TYPE Old: &CUR_DTTM / New: &NEW_DTTM or &NEW_DTTM1

Perfect

Thanks
