I don't believe there is a defined algorithm for this in SAS Base, you'll have to determine the algorithm and implement it yourself.

Then I would analyse the transactions for those cards over the same period to see if I could find a common behaviour pattern linked to CPP for these cards versus 'normal' transaction behaviour.</P> <P>&nbsp;</P> <P>I would then develop and test an algorithm against a population of credit card transactions to measure how effective it is in identifying CPP. This is not a trivial task and will involve processing millions of card transactions and many weeks of effort with a lot of trial and error to come up with an effective solution.</P> <P>&nbsp;</P> <P>Note: every credit card providers' transaction data is different so it is highly-unlikely an off-the-shelf solution will work without a lot of customisation. DIY (Do It Yourself) is probably a better bet.</P> Sat, 02 Feb 2019 21:05:32 GMT https://communities.sas.com/t5/New-SAS-User/Common-Purchase-Point-in-fraud-analytics-for-credit-card/m-p/532320#M6015 SASKiwi 2019-02-02T21:05:32Z https://communities.sas.com/t5/New-SAS-User/Common-Purchase-Point-in-fraud-analytics-for-credit-card/m-p/533119#M6141 Thank you so much.
