I need to use as a base the sum of some previous payroll rule categories.
I tried the following code but it doesn't add anything:
result = payslip._sum_category('ALW', payslip.date_from, to_date=payslip.date_to)
Additionally, I tried the following code but I can only access the salary rules and not the rule categories:
payslips = contract.env['hr.payslip'].search([
('employee_id', '=', contract.employee_id.id),
('date_from', '>=', payslip.date_from),
('date_to', '>=', payslip.date_to),
('company_id', '=', contract.company_id.id),
])
result= month_payslips._get_line_values(['ALW', vals_list=['total'], compute_sum=True)['ALW']['sum']['total']
