To monitor monetary instruments, we recommend you use the BSA review process and wherever you see a transaction where a monetary instrument is purchased with cash in, create a Tracker using a specific Memo Type code (we recommend you create a Memo Type "MI" for "Monetary Instrument").
Then you can use the "Print Member Trackers" feature to pull a Tracker report that will show you all of your monetary instruments for the time period selected, based on Memo Type.
