Absence for more than 30 days (vacation)

Hi All

If an employee is to be absent during future payroll periods, for example, because of leave, you can pay the employee in advance for the period of the absence.

My employee is to be absent from 1/5/2016 to 4/6/2016 (dd/mm/yyyy) = 35 days.

Off cycle run is ok for 35 days.

I´m facing problem when i have to discount days not worked.

In May, this is the payroll

1010 Sueldo Basico                    8.000,00

2030 Días Desc. por Vacacion      30,00          8.000,00-

It´s 30 because I fill with 3 in V_T7AR45_C

But in June,

1010 Sueldo Basico                     8.000,00

2030 Días Desc. por Vacacion      4,00          1.066,67-

There is  a difference of 1 day.

Kindly need your guidance.

Regards,

Daniela
