Merchant generated number used to identify the transaction.
This property is required for Debit transaction clearing, and should contain a unique 6-digit trace number identifying the transaction. The merchant application should generate a unique number for each Debit or EBT transaction. If a Debit or EBT transaction is voided or reversed, the ReceiptNumber of the original transaction should be used. The receipt number must be passed to the FDMS Host on both the Debit/EBT authorization request and the batch settlement detail. It must also be printed on the customer receipt. Used such, this number satisfies Debit Network Provider requirements.
