This custom function can be used for:

1) Autoenter a serial number that increments daily
2) the format of the serial number is essentially: YYYYMMDD##
3) the serial number may have how many digits (#) you choosed
4) the format can be specified, so to have:
format = 1: MMDDYYYY##
format = 2: DDMMYYYY##
format = "": YYYYMMDD## <--this is the default result

The Auto-Enter field must be setted to always evaluate;
the custom function isn't recursive, so you can use it as a simple calc;
the custom function will work only with FMP8 and above.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

Now I am receiving the following:
