!!Post test data in the form of a datastep!!
Its not hard, and it saves lots of questions!!!
As such I am guessing dates are dates:
data have; customer_id=50095; sub_table_date="22Dec2015"d; run; data want; set have; sat_date=sub_table_date; do while (weekday(sat_date) ne 7); sat_date=sat_date-1; end; format sub_table_date sat_date date9.; run;
data have;
input customer_id sub_table_date :date9.;
datalines;
50095 22Dec2015
50206 10Jan2016
50220 26May2016
;
data want;
set have;
do _n_=sub_table_date by -1 until(weekday(_n_)=7);
if weekday(_n_)=7 then Saturday_before_dt=_n_;
end;
format sub_table_date Saturday_before_dt date9.;
run;
