Hi,

We can use the following code for creating a server action.

<record id="model_test_record_id" model="ir.actions.server">

            <field name="name">Record Name</field>

            <field name="model_id" ref="module_name.model_model_name"/>

            <field name="binding_model_id" ref="module_name.model_model_name"/>

            <field name="binding_view_types">form</field>

            <field name="state">code</field>

            <field name="code">action = records.demo_server_action()</field>

 </record>

We can define the server action demo_server_action() on the model.name model

Use the following code to call the server action from a function.

@api.model
def function_name(self):
    model_id.demo_server_action()

Regards
