https://communities.sas.com/t5/ODS-and-Base-Reporting/Proc-Compare-Missing-outdif-record/m-p/29831#M4527 Hello,<BR /> <BR /> I am comparing two data sets using proc compare. I am outputing results to display all three recods (base, compare, dif). For some reason, some 'base' and 'compare' records have a matching ID, but there is no Dif record displayed. About half my population is showing a "Dif' record in the out file, but for others is not. Can anyone offer any explanation as why this may be occuring. note: Data is sorted before compare.<BR /> <BR /> proc compare base=in.data_1 compare=in.data_2<BR /> outbase outcomp outdif out=out.data_3<BR /> <BR /> id ID; Tue, 08 Jul 2008 23:45:52 GMT deleted_user 2008-07-08T23:45:52Z https://communities.sas.com/t5/ODS-and-Base-Reporting/Proc-Compare-Missing-outdif-record/m-p/29831#M4527 Hello,<BR /> <BR /> I am comparing two data sets using proc compare.
