The order was placed successfully and i raised invoice with 'Capture Online' its also completed successfully. When i try to refund with 'Refund online' it throws error as '
Please help ASAP.
When we examine transaction 2251674769, it was authorized for $105 and then we received a priorAuthCapture which set the status to Captured/Pending Settlement. Until this transaction settles, you cannot issue a refund, you can only void the entire transaction. Transactions settle once a day after the cut-off time configured in the Merchant Interface.
I hopes this help isolate your issue.
