Each EFT file must have a unique and sequential ‘file creation number’. I need to alter this starting value.

The File Creation Number is a 4 digit number set within the Merchant Account information.

In the example above, setting the ‘last transaction number’ to 2, means the next EFT file creation will be 0003.

This number must begin at 0001 for all new accounts If a file creation number is skipped for any reason, your bank may reject the entire EFT file from processing. A file creation number can never be repeated When the file creation number gets to 9999, the next number will be 0001. (I know, this breaks the rule above, but as we know, all rules are meant to be broken in special situations)
