Hi,

1- By using the following code, you can make the cost field read-only for all users

<record id="product_template_form_view" model="ir.ui.view">

        <field name="name">product.template.view.form.inherit</field>

        <field name="model">product.template</field>

        <field name="inherit_id" ref="product.product_template_only_form_view"/>

        <field name="arch" type="xml">

            <xpath expr="//field[@name='standard_price']" position="attributes">

                <attribute name="readonly">1</attribute>

            </xpath>

        </field>

</record>

2- By using the studio.

Or by adding the readonly attribute in the product view, you can achieve this.

Hope it helps

Hi,

You can make the "Cost" field (standard_price) read-only for all users using both

1. By using Studio

You can also set it based on a condition

2. By using Code

<record id="product_template_only_form_view"
        model="ir.ui.view">
    <field name="name">product.template.form.readonly.cost</field>
    <field name="model">product.template</field>
    <field name="inherit_id" ref="product.product_template_only_form_view"/>
    <field name="arch" type="xml">
        <xpath expr="//field[@name='standard_price']" position="attributes">
            <attribute name="readonly">1</attribute>
        </xpath>
    </field>
