The task Number must be numeric. Hence, acceptable values are:
- integers (1, 2, 3, 4, etc.)
- decimal numbers (for example, 7.1)
AceProject will allow you to enter a decimal task number using either the comma (“,”) or the period (“.”) as the decimal separator. After saving the task, AceProject will show task numbers using your personal Date Format selection.
It is not possible to enter a task number with two or several decimal separators.
