When I try to install the module where the following inherited view is defined i get the error 

❌ 
Field "show_forecasted_qty_status_button" does not exist in model "product.template"

I checked 

  •     https://www.odoo.com/es_ES/forum/ayuda-1/error-partner-bank-id-cannot-be-located-in-parent-view-odoo19-292645
  • https://www.odoo.com/es_ES/forum/ayuda-1/error-msg-element-xpath-expr-cannot-be-located-in-parent-view-213940

And I verified that reference to the XML ID in my view is correct. The field show_forecasted_qty_status_button is listed from the debugger in the Product Template view.

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <record id="product_template_procurement_form_hide_forecast" model="ir.ui.view">
        <field name="name">product.template.procurement.form.hide.forecast</field>
        <field name="model">product.template</field>
        <field name="inherit_id" ref="stock.product_template_form_view_procurement_button" />  
        <field name="priority">14</field>
        <field name="arch" type="xml">
            <xpath expr="//field[@name='show_forecasted_qty_status_button']" position="attributes">
                <attribute name="value">0</attribute>
            </xpath>
        </field>
    </record>
</odoo>


The other thing I tried without success was to inherit the model in order to overwrite the method of the computed field. But the log entry was not listed in the log.

class ProductTemplate( models.Model ):

    _logger = logging.getLogger(__name__)

    _inherit = ['product.template']

    """
        Removes the forecasted quantity button in product template view

        @see commit abf1ee63f41094a313ead96caccc284c0b233244
    """
    @api.depends('is_storable')
    def _compute_show_qty_status_button(self):
        self._logger.info('###################################### _compute_show_qty_status_button ########################################')
        for template in self:
            template.show_on_hand_qty_status_button = template.is_storable
            template.show_forecasted_qty_status_button = False

Hello
I've test the same scenario in my local V18 env and not getting any error while installing or upgrading the module.

The issue is that in Odoo 18, the field show_forecasted_qty_status_button may not be defined directly in the stock.product_template_form_view_procurement_button view - it may be added by a different inherited view layer. Here is how to debug and fix this:

Step 1: Find which view actually contains this field
With Developer Mode enabled:
1. Open a product form
2. Click the debug menu (bug icon) > Edit View
3. Look through the combined view to find which ir.ui.view ID actually renders the show_forecasted_qty_status_button field
4. Inherit THAT view instead of stock.product_template_form_view_procurement_button

Step 2: Check the field definition
In Odoo 18, check addons/stock/models/product.py for the exact field definition. The field may be defined as a computed field only available when certain conditions are met (e.g., the product must be storable). Your XPath may fail if the field is not present in the view arch at install time.

Step 3: Fix your XPath - target a different expression
Instead of targeting the field itself, try targeting the button widget directly. In the final view, look for the button that shows the forecasted qty and target its name attribute.

Step 4: Priority matters
Your view has priority 14. If the view that adds show_forecasted_qty_status_button also has a low priority, it may not have been applied yet when your view tries to reference it. Try increasing your priority to a higher number (e.g., 50) so it applies after the base views.

Most likely fix:
The field is probably added by a different stock view, not stock.product_template_form_view_procurement_button. Use the Odoo debug view inspector to find the correct inherit_id, then change your inherit_id to that view.

Hello,

It looks like the issue is not with the XML ID itself, but with the fact that the field show_forecasted_qty_status_button is probably not present in the inherited view architecture (stock.product_template_form_view_procurement_button) at the moment your XPath is applied.

In Odoo 18, some of these quantity status fields/buttons are added through layered inherited views and may not be directly available in that specific parent view.

Also, in your Python override, the compute method name should exactly match the original method definition from the source model, otherwise Odoo will not execute your custom logic.

You may want to:

  • verify the final inherited view structure using Developer Mode,
  • inherit the correct intermediate view,
  • or target the button element directly instead of the field.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion.
