delete filter not working with character values

[Q1983]

data legacy_detail;

set rad_0;

where coalesce(APPL_RECV_BY_LEND_DT,RECV_STAT_DT) >='01jan2015'd

     or PRICE_Lock_date >='01jan2015'd   or

           LOCK_IN_DT >='01jan2015'd   and STAT_AGGR_CD = '' ;

if STAT_AGGR_CD in ('Purchased', 'Denied') then delete;

if platform in ('RAD','LNS') then delete;

run;

STAT_ACCR_CD is a character variable. The choices of 'Purchased', 'Denied' are also character variables. Yet for some reason the filter does not work. It does not eliminate those with Purchased and Denied. Has this ever happened to anyone and is this a bug with sas. What am I doing wrong because the coalesce filter is working.

[Q1983]

Cancel question, evidently the character for this table was case sensitive, never happened before but I believe I figured it out

Try:

if propcase(strip(STAT_AGGR_CD)) in ('Purchased', 'Denied') then delete;

Is this working?
