<record id="hr_payroll_rules_hs_40" model="hr.salary.rule">
<field name="category_id" ref="hs"/>
<field name="name">HS 40%</field>
<field name="code">HS40</field>
<field name='company_id' eval='lambda self:self.env.company.id' />
<field name="sequence">1022</field>
<field name="appears_on_payslip">True</field>
<field name="condition_select">python</field>
<field name="condition_python">if inputs.HS40.amount !=0:
result = True
</field>
<field name="amount_select">code</field>
<field name="amount_python_compute">result = inputs.HS40.amount*1.4*(categories.BASE + categories.INDM)/173.3333
</field>

but I have problem , how can i do

You can't do that from XML, You have to do it from python:

company_id = fields.Many2one('res.company', default=lambda self: self.env.company)

If the field already set then you can exclude it in XML and It will take the current company by default.

j'AI FAIT CELA mais y'a un souci en multi societé , le fichier data est chargé dans un autre societé different du societé en cours
