Hi, i confused when i try to replace data in demo data. I wanna change the data in odoo/addons/product/product_data.xml for demo data Precision like this :

<record forcecreate="True" id="decimal_price" model="decimal.precision">

<field name="name">Product Price</field>

<field name="digits">2</field>

</record>

<record forcecreate="True" id="decimal_discount" model="decimal.precision">

<field name="name">Discount</field>

<field name="digits">2</field>

</record>

<record forcecreate="True" id="decimal_account" model="decimal.precision">

<field name="name">Account</field>

<field name="digits">2</field>

</record>

<record forcecreate="True" id="decimal_stock_weight" model="decimal.precision">

<field name="name">Stock Weight</field>

<field name="digits">2</field>

</record>

<record forcecreate="True" id="decimal_product_uom" model="decimal.precision">

<field name="name">Product Unit of Measure</field>

<field name="digits" eval="3"/>

</record>

<record forcecreate="True" id="decimal_product_uos" model="decimal.precision">

<field name="name">Product UoS</field>

<field name="digits" eval="3"/>

</record>

and i want to replace with create new demo data for Precision. I can't find how to change replace demo data with inherit or any else except delete and create new.

Thanks,
