Error message

You cannot perform this action on an account that contains journal items.

What it means

UserError raised by the @api.ondelete(at_uninstall=False) hook _unlink_except_default() on barcodes.nomenclature when the unlink recordset includes the record referenced by the external ID barcodes.default_barcode_nomenclature. Odoo keeps this shipped nomenclature as a guaranteed default; the guard blocks its deletion during normal use but allows it at module uninstall.

Solutions

1. Exclude the default record from the delete set
2. If you want a different default, point the barcodes.default_barcode_nomenclature XMLID reference elsewhere (a module override) — do not just unlink it
3. Adjust cleanup scripts to filter by id != env.ref('barcodes.default_barcode_nomenclature').id

Example fix

# before
env['barcodes.nomenclature'].search([]).unlink()

# after
default = env.ref('barcodes.default_barcode_nomenclature', raise_if_not_found=False)
noms = env['barcodes.nomenclature'].search([])
(noms - default).unlink() if default else noms.unlink()

default = self.env.ref('barcodes.default_barcode_nomenclature', raise_if_not_found=False)
noms = self.env['barcodes.nomenclature'].search([])
if default:
    noms -= default
noms.unlink()

from odoo.exceptions import UserError
try:
    noms.unlink()
except UserError as e:
    if 'default barcode nomenclature' in str(e):
        # retry without the default record
        (noms - self.env.ref('barcodes.default_barcode_nomenclature')).unlink()
    else:
        raise

When it happens

Trigger: Calling unlink() on a recordset containing the default nomenclature — deleting it from the Barcode Nomenclature list view, or a server script purging all nomenclatures (e.g. env['barcodes.nomenclature'].search([]).unlink()).

Common situations: Data-cleanup scripts that unlink everything; admins deleting 'unused' nomenclatures; duplicated nomenclature lists where users select-all and delete.
