what is ACH/EFT Reference No. field?

AI generated answer (using internal Slack threads):

The ACH/EFT Reference No. field is typically used in the context of electronic payments. It is a unique identifier for a transaction in an ACH (Automated Clearing House) or EFT (Electronic Funds Transfer) payment. This reference number is often used to track or reference the payment in the banking system. In the context of NetSuite, this reference number can be included in the payment file that is generated for electronic payments. The placement and usage of this reference number can depend on the specific requirements of the bank or financial institution that is processing the payment. For example, in the NACHA file format (a common format for ACH payments), this reference number could potentially be placed in the 'Individual identification number' field in positions 40-54 of the entry detail record. However, whether or not this is possible can depend on a variety of factors, including the specific layout and requirements of the payment file, where the reference number is stored in relation to the payment record, and whether there is space in the payment file to include this additional information. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
