RB S - S, JE0, K@@, X05 - This code is a sequence error

Verify the sequence of records in a batch. The order of the records should be header, parameter, detail, and trailer. The system rejects a batch that does not conform to the order of records. The batch should contain at least one valid transaction that was not deleted/voided.

Possible Causes	Solutions
No valid transactions	Determine if the batch contains at least one valid transaction. If a valid transaction is present, retain and re-transmit the batch. If the batch contains only one transaction that is voided and has a zero total amount, delete the batch.
VeriFone: Baud speed issue	If the RB occurs on a 330 or 380 (specifically 380 software VT13PA3), check the baud speed (fields 542/543). If the baud speed is set to 300 baud (542/543=0), change to 1200 baud (542/543=1). This is known to clear up chronic RB KK@@ sequence errors.
Corrupt Merchant data	Print out the merchant data screen, delete it, and re-enter it.
Incorrect Date and Time in the terminal	Retain the batch, correct the date and time in the terminal, and re-transmit.
Unknown	Acquirer: If the sequence error persists, refer to Merchant Services. Merchant: Escalate the error to research or to a supervisor.
