Question

%let months_back = %sysget(months_back);

data;
        m = intnx('month', "&sysdate9"d, -&months_back - 2, 'begin');
        m = intnx('day', put(m, date9.), 26, 'same');
        m2back = put(m, yymmddd10.);
        put m2back;
run;

NOTE: Character values have been converted to numeric values at the
places given by: (Line):(Column).
5:19 NOTE: Invalid numeric data, ’01OCT2012′ , at line 5 column 19.

I really don’t know why this go wrong. The date string is numeric data?

Answer 1

PUT(m, date9.) is the culprit here. The 2nd argument of INTNX needs to be numeric (i.e. a date), the PUT function always returns a character value, in this instance ’01OCT2012′. Just take out the PUT function completely and the code should work.

m = intnx('day', m, 26, 'same');
