HI,
Utilize odoo create orm method:  Odoo Create ORM Method
Thanks

This method will create a new record in the target model and populate its fields with data from the current model.

from odoo import models, fields

class YourModel(models.Model):
    _name = 'your.model'
    _description = 'Your Model'

    name = fields.Char(string='Name')
    description = fields.Text(string='Description')
    related_field = fields.Many2one('other.model', string='Related Model')

    def action_create_new_record(self):
        for record in self:
            # Create a new record in the other model
            self.env['other.model'].create({
                'name': record.name,  # Pass data from the current model
                'description': record.description,
                'related_field': record.id,
            })



Add a button to your form view in the XML file. Use the type="object" attribute to call a Python method when the button is clicked.


<record id="view_your_model_form" model="ir.ui.view">
    <field name="name">your.model.form</field>
    <field name="model">your.model</field>
    <field name="arch" type="xml">
        <form string="Your Model">
            <header>
                <button name="action_create_new_record" type="object" string="Create Record" class="oe_highlight"/>
            </header>
            <sheet>
                <!-- Your form fields go here -->
            </sheet>
        </form>
    </field>
</record>


When you click the "Create Record" button on the form view of your current model, a new record will be created in the target model using the data from the current record.
