How can I see the total cash given as change on CATM transactions for a given period of time?
The Integrated ATM transactions on the Payment Report will have a negative cash entry associated if there was cashback given.
Navigate to Reports -> Sales -> Payment -> CSV Export
You can download the report for a specific time period (Month) and cross reference (vlookup) the Integrated ATM Ticket ID with an associated negative Cash transaction and Sum.
Column G will have the Payment Type, K Ticket Id, and N Gross Receipts.
