ACH R84- What is this?

ACH (Automated Clearing House) code R84 indicates that a transaction has been rejected because the amount is invalid. This could happen if the amount is negative, zero, or exceeds a specific limit set by the receiving bank or financial institution.
This code is typically used in ACH transactions in the United States, which are electronic payments that move money between bank accounts. When a trade with the R84 code is rejected, the price has not been completed, and the funds have not been transferred.

To resolve this issue, the sender of the payment should double-check the amount being sent and ensure it is accurate and within limits set by the receiving bank. If the problem persists, the sender should contact their bank or financial institution for further assistance in resolving the issue.
