@Babloo

Unbalance brackets:

Remove one of the closing brackets after today())

[Vibcom]

Place close brackets before > .change if condition to--

if input((cats(renewal_date,"2018"),date9.)) > today() then new_renewel_date=input(cats(renewel_date,"2019"),date9.);

[gamotte]

Also, you have written "renewel" instead of "renewal" at several places.

Edit : I guess you want

data want;
set have;
if input(cats(renewal_date,"2018"),date9.) > today() then new_renewal_date=input(cats(renewal_date,"2019"),date9.);
else new_renewal_date=input(cats(renewal_date,"2018"),date9.);
run;

Clue:

ERROR 79-322: Expecting a )

If you are using the Enhanced editor you can find matching ( or not matched parentheses by placing the cursor on either the ( or ) and pressing CTRL 9. If you do so on the "input(" ( then you will find that the matching ) is after the today(). In other words the INPUT is being told to include "> today()" in some form. You likely meant there to be a ( before input to go along with the IF.

if (input(cats(renewal_date,"2018"),date9.) > today())
