While creating an adjustment through the Order Adjustment Feed, you may have received one of the following error messages:
Error 10812 occurs when the refund amount you are requesting for the tax or shipping tax component of an order exceeds the amount that can be refunded or if only the tax or shipping tax component of an order is provided or vice versa. Common reasons why your requested refund might be too high include the following:
For example, if a customer pays $2 for shipping tax, you can refund up to $2 toward the shipping tax component of the order. If you refund $1.50 of the shipping tax, the customer's shipping tax balance is $0.50. Any future refunds for the shipping tax cannot exceed that $0.50 balance. If a customer pays $10 for an item and $2 in tax, if you are not tax refund eligible, you cannot refund the $2 in tax unless you also refund $10 for the item.
To view the current balance for any component in an order, you can search for the order on the Manage Orders page in Seller Central.
To resolve this error, please resubmit your data with a refund amount that is less than or equal to the customer's current balance.
