I need to get the option to select a product public category from the following view:

product.pricelist.item.form 

Could someone advise me on how to do this ?

I tried to add the following line to the view

<field name="public_categ_id"/>.

I got the following error message

ValidateError

Field(s) `arch` failed against a constraint: Invalid view definition

Error details:
Field `public_categ_id` does not exist

Error context:
View `product.pricelist.item.form_adlibitom`
[view_id: 2602, xml_id: n/a, model: product.pricelist.item, parent_id: n/a]
