Error: Data could not be saved. There is an error in XML document (1,443) when refunding a credit card payment that is older than 60 days
In November of 2014 Blackbaud Merchant Services increased the refund date from 60 days to 180 days. If you attempt to refund a payment that was entered before this date and is older than 60 days but less than 180 days the error will occur. The workaround is to manually refund the credit card.
