I changed all the "stucturing" rules to require at least two deposits in order for it to hit. 2 deposits in a week is a hit, or 4 deposits in 30 days is a hit. Otherwise we have "structuring" hits when a person makes a single cash deposit of $8,000 over the course of a month. We tinkered with it repeatedly until we reduced our flags requiring manual review from 120 a day down to about 20 a day. You can also just change the risk threshold that requires manual review until you are getting the right set of transactions every day.
