I am trying to to add the product barcode number to the Qweb BoM Overview page. The page where you can unfold sub-boms or print the report.

I have created two views for the table and the table lines to inherit from the original templates.

I have added dependencies and assets in my manifest.

'assets': { 'web.assets_backend': [ 'manufacturing/views/bom_overview_table_inherit.xml', 'manufacturing/views/bom_overview_line_inherit.xml', ], },

I don't know why, but the field does not seem to be showing up in the Overview. 

Have I missed something?
