Entering Holiday & Vacation for Salary Personnel

QBooks wouldn't let me enter hours for three different types of hours on a salaried employee; reg hours, vacation and holiday hours. It would not compute the 3 way split for the employee. As usual there was no time left to research the issue, so to ensure that his vacation time was tracked correctly, I entered all of his time as 2 entries (reg hours and vacation hours). But I would like to for future entries to show all types of hours worked for the salary personnel. so is there something I need to do differently to ensure that the records are calculated with all 3 payroll items; reg hour, vacation & holiday hours?
