I am assuming when you stated "Scrub the list" you are referring to running the most current OFAC list against your customer database. My understanding, users of Jack Henry have that feature automatically built in. Other banks are using other software such as Choicepoint/Bridger to "scrub" the customer database against OFAC or other Automated AML software. Check with your IT Department and have a technician convert the OFAC list into a consolidated index text file that can be filtered/scrub against your customer database.
Hope that helps.
These are just my own opinions...my body is here but my mind has already teed off...FORE!
