I am having difficulty where obs having missing values. For obs e=. and f=. For these obs, prec value should be missing

proc sql;
create table want as
select *,
(select max(lengthn(scan(put(value, best32.), 2, "."))) from have where not missing(value) group by var) as prec
from have
;
quit;
proc sql;
create table want as
select
*,
case when value is missing then .
else max(lengthn(scan(put(value, best32.), 2, "."))) end as prec
from have
group by var;
quit;
please try below code
proc sql;
create table want as select a.*, case when value ne . and b.dec ne . then b.dec when value ne . and b.dec eq . then 0 else . end as prec from have as a left join
(select distinct var, case when value ne . and scan(put(value,best.),2,'.') ne '' then max(length(scan(put(value,best.),2,'.'))) else . end as dec from have group by var having calculated dec ne .) as b on a.var=b.var;
quit;
