Problem Note 41011: Use of HAVING clause with SQL GROUP BY may return incorrect results
 |  |  |  |  |
A parallel GROUP BY clause can generate incorrect results for variables with non-standard length columns if a HAVING clause is used.
The following code illustrates a case that can produce incorrect results in columns YEAR and SUM(PAY_MTS):
libname foo sasspds 'public' server=hostname.5400 user='anonymous'
ip=yes libgen=yes;
data foo.mytest;
length year 3 abc 3 paid $1 chargeable $1 pay_mts 8;
input year abc paid $ chargeable $ pay_mts;
cards;
2010 100 y n 200
;
run;
proc sql;
select distinct abc, chargeable, paid, year, sum(pay_mts)
from foo.mytest
group by abc, chargeable, paid, year having count(*) gt 0;
quit;
