We had a Primavera P6 support question today about how to persuade P6 to be accurate to the cent and partial hour. If you are trying to prevent P6 from rounding to the nearest dollar or hour, there are two places to change your preferences to deal with cents or partial dollars & hours.
The first is in User Preferences, where you can choose the number of decimals of your time unit:
Go to Edit –> User Preferences
In the Time Units Tab, adjust the number of decimals accordingly.
The second place is in Currencies, where you can choose the number of decimals in your currency unit:
Go to Admin –> Currencies
In the Appearance tab, adjust the number of decimals to your preference.
