How can we calculate Overtime in openerp

Hi...My requirement is result = total wage will be divided into total working days of month * total present days of employee of this month..I have a own modules and it contains total working day and total present of month for each employee..Kindly tell me the solution to achieve my result

Thanks For Reply Same procedure i already i followed but yet i didn't get result "result=(contract.wage/31)*worked_days.Unpaid.number_of_days" this code is correct or not i'm using OpenERP 7 , help me. Thanks & Regards Sridharan G Chennai

@Mustufa Rangwala the code result=(contract.wage/31)*worked_days.Unpaid.number_of_days calculate the total of Unpaid leaves but we need total at that month and there is error when employee do not have an Unpaid leave , how to solve this problems , Or if we can build new module to calculate that , Please help ....

@Maath I am also having the same issue.. i think we can have a python condition check because it will be always "TRUE" so it wont allow if they doesnt have unpaid leaves.. i tried that condition also but it failed because of having "Unpaid" object

@Ajmal , Oky , and what about the total leaves for each month I try with payslip Bach and every thing is Oky and there is no error

@Maath Unpaid rules added in Salary Structure for an employee means, it didn't accept batch concept same error Python code Error Plese check it my DB

@all : How to deduct the salary of the employee if he is absent without taking any leaves.?? Plz Help

@all: Error when using this python code if employee dont have any leave. Is there a method to solve this.??

@Raminder Pal Singh I think there is may be error in the system , But when I create a Bach for salary then there is no error , I am also need for deduct the salary of the employee if he is absent without taking any leaves , I think we should create new module .. if you want to share our work and contact on skype I think there is other developer want to do the same .

@maath the error remains when we creates salary batch.

@Raminder Pal Singh I think there is may be error in the system , I think we should create new module .. if you want to share the work then will contact on skype
