The system was not automatically adding new employees created after the accrual allocations. So we created an automation rule (execute code) to add and allocate employees to the accrual system.

employee = record

employee_name = employee.name

current_year = datetime.date.today().year

leave_type = env['hr.leave.type'].browse(8) #8 is the id of the Leave or the Time Off Type

allocation_obj = env['hr.leave.allocation']

accrual_plan = env['hr.leave.accrual.plan'].browse(4) #4 is the id of the Accrual type created in the system

if leave_type:

    existing_allocation = allocation_obj.search([

        ('employee_id', '=', employee.id),

        ('holiday_status_id', '=', leave_type.id),

        ('state', '=', 'validate'),

        ('date_to', '=', f'{current_year}-12-31'),

    ], limit=1)

    if not existing_allocation:

        allocation_obj.create({

            'name': f'Emergency Leave Allocation for {employee_name} - {current_year}',

            'employee_id': employee.id,

            'holiday_status_id': leave_type.id,

            'allocation_type': 'accrual',

            'accrual_plan_id': accrual_plan.id,

            'number_of_days': 0,

            'date_from':datetime.date.today(),

        })

In this way, the new employees will be added and they will have the leaves created automatically based on the accrual configuration.
