How to choose more important value from one column for value in corresponding column in SAS Enterprise Guide?

This could definitely be done more elegantly. But this should work just fine.

data have;
    input VAL1 $2. ID VAL2 $1.;
    datalines;
P1 123 P
P1 123 P
P1 123 S
S2 44 C
S2 44 S
GG 44 P
P1 58 S
P1 58 S
;
run;

proc sort data=have out=sorted nodupkey;
by ID descending VAL2;
run;

data want;
    set sorted;
    by ID;
    if VAL2 in ('P' 'C') then output;
    else if last.ID then output;
run;
