Report of All Recurring Items
As an admin user, you can view a list of all the recurring items in the current week's orders. This report will tell you if there are any issues with recurring items- if a customer has a recurring schedule for an item and the status is not 'good', chances are you didn't have enough of the product in stock!
To fix this, you can manually edit a customers order (if you get more of the product), and in the future just be sure to carry enough of the product in stock.
You can find this report under Reports->Recurring Items, or by using the quick search feature to find "Recurring Items".
