This report will show you a summary of the number of times a particular code has been used and the total discount across all orders where this code has been used within the date range selected. You can alter the date range by selecting the date and choosing a new date from the drop down calendar. It is defaulted to "Received date" however, if you want to filter by "Revenue date" instead you can select "Add filter" and can toggle on "Revenue date" instead. From the filter pop up you can also toggle on the "Promo code" filter to then filter by a specific promo code too if needed...
The report has the following columns:
Code - the code for the promo code (archived promo codes are also included)
Total times used - number of orders where this promo code was applied
Total discount across all orders - this totals the amount of money that came off the orders after applying the promo code
To see a further breakdown by specific orders you can use the Promo Code Usage Breakdown report. Please view guide here for more info.
