Hi,

you can use sequence number generator for that.

<data noupdate="1">
    <record id="sequence_id" model="ir.sequence">
        <field name="name">Sequence Name</field>
        <field name="code">your.model</field>
        <field name="prefix"></field>
        <field name="number_next">0</field>
        <field name="number_increment">1</field>
        <field name="padding">1</field>
    </record>
</data>

You can use this sequence in Python by

serial_no = fields.Integer(string="ID", default=lambda self: self.env['ir.sequence'].next_by_code('your.model'))

Thank you
