For this reason you can't use match codes generated with different sensitivities for joining/lookup.</P> <P>I think of match codes as grouping/clustering values. The lower the sensitivity the more source values will get grouped into the same match code. For this reason if you generate in both tables match codes with a lower sensitivity then you'll get more matches when joining.</P> Tue, 26 Mar 2019 23:18:01 GMT Patrick 2019-03-26T23:18:01Z https://communities.sas.com/t5/SAS-Data-Management/Dataflux-Match-Codes/m-p/546121#M16808 <P>How to find more matches through simpler match codes. Will match codes with a lower sensitivity value be matched to a higher number of match codes with higher sensitivity. How is Data Joining configured in this context?</P> Tue, 26 Mar 2019 13:04:45 GMT https://communities.sas.com/t5/SAS-Data-Management/Dataflux-Match-Codes/m-p/546121#M16808 Bastian 2019-03-26T13:04:45Z https://communities.sas.com/t5/SAS-Data-Management/Dataflux-Match-Codes/m-p/546349#M16809 <P><a href="https://communities.sas.com/t5/user/viewprofilepage/user-id/264605">@Bastian</a>&nbsp;</P> <P>As I understand it the match code generated depends on the sensitivity.
