Hi,

Try the following code for removing the product description from the invoice line.

from odoo import _, api, fields, models

class AccountMoveLine(models.Model):

    _inherit = 'account.move.line'

    @api.depends('product_id', 'move_id.payment_reference')

    def _compute_name(self):

        def get_clean_name(line):

            values = []

            if line.partner_id.lang:

                product = line.product_id.with_context(lang=line.partner_id.lang)

            else:

                product = line.product_id

            if not product:

                return False

            # Add internal reference

            if product.default_code:

                values.append(f"[{product.default_code}]")

            # Add product name

            values.append(product.name or '')

            # Add variant attributes

            if product.product_template_attribute_value_ids:

                variant_names = ', '.join(

                    v.name for v in product.product_template_attribute_value_ids

                )

                values.append(variant_names)

            return ' '.join(values).strip()

        term_by_move = (self.move_id.line_ids | self).filtered(

            lambda l: l.display_type == 'payment_term'

        ).sorted(lambda l: l.date_maturity or date.max).grouped('move_id')

        for line in self.filtered(lambda l: l.move_id.inalterable_hash is False):

            if line.display_type == 'payment_term':

                term_lines = term_by_move.get(line.move_id, self.env['account.move.line'])

                n_terms = len(line.move_id.invoice_payment_term_id.line_ids)

                name = line.move_id.payment_reference or False

                if n_terms > 1:

                    index = term_lines._ids.index(line.id) if line in term_lines else len(term_lines)

                    name = _('%s installment #%s', name if name else '', index + 1).lstrip()

                if n_terms > 1 or not line.name or line._origin.name == line._origin.move_id.payment_reference:

                    line.name = name

            if not line.product_id or line.display_type in ('line_section', 'line_note'):

                continue

            if not line.name or line._origin.name == get_clean_name(line._origin):

                line.name = get_clean_name(line)

Hello, Nico

    To show only the product name, internal reference, and variant to be displayed—without the product description once

    user add a product in Invoice.

    Please create a custom module and add a below code of snippet

        1) Create a Module, after that create a account_move_line.py file and add it in folder called 'models'.

//Code in comment//

2) As you can see in below image that I have cretaed 3 new products, One Product without variants and Internal Reference,

   Second Product with Variants only and third product with Internal Reference.

3) For the report Please check below image.

Hope this helps !
