datalines;
123,a,0
123,a,0
123,r,1 /**<- replace with last value (30) when "r" or "ra" */
123,r,20 /**<- replace with last value (30) when "r" or "ra" */
123,ra,30
123,w,4
234,b,1
234,c,20
234,ra,400 /**<- replace with last value (200) when "r" or "ra" */
234,r,200
234,c,200

set have(where =(description in ('r','ra')));
by account;if last.account then output ;run;
proc sql;
update have
set amount=(select amount from test where test.account=have.account )
