If using the standard Windows setting of 2 digits after the decimal, you could only enter in the part cost as beinng $0.01

Just as the date format, the currency format, and the time format is dictated by your computer's system settings (AyaNova v3 Manual section "Currency, Date and Time Display and Selection" starting on page 67) so too is the number of digits to display after the decimal point.

To change currency fields, open Control Panel -> Regional Settings -> change for the currency No. of digits to use after decimal to 3

Reboot the computer.

Now when you run AyaNova, it will display currency fields with 3 decimal places so you can enter in amounts that use less than a penny.

If printing reports still displays using 2 digits, you will need to customize the report to format the string to display taking the computer's system settings, instead of a set setting.
