If you click on the "View" button for a single recurring donation, you're taken to a Recurring Donation Detail page. This page shows details about this recurring donation such as history, amount, and fund, as well as the ability to stop the donation.
There are several items on the donation detail page that might help admins assess, and if needed, repair a recurring donation. The left side of the screen shows donor information, and the upper right side of the screen shows the fund breakdown as well as the recurring schedule. The bottom of the screen shows the history of this recurring donation. Clicking on an individual donation will expand to show transactions (how many times the donation was tried - successful donations will only have one, whereas unsuccessful donations might have more). Further clicking on transactions will show the details of the transaction from the bank. This will include any error messages from the bank.
Stopping a recurring donation
To stop a recurring donation from the detail page, click the STOP button in the top-right corner of the detail page. After the confirmation, this will permanently stop all future donations.
Refunding a specific donation
To refund a donation in a recurring profile, find the donation in the history, and press the "Refund" link at the far right of the donation.
