`related_partner_ids` is used in the form view of account.payment https://github.com/odoo/odoo/blob/43fccd7aaa83117c95babc52d60dd1c26b28335a/addons/payment/views/account_payment_views.xml#L14 It is only needed for electronic payments to display the payment token ids (as part of its domain) https://github.com/odoo/odoo/blob/45f5167b956521f0a183ff1b1cc75fa1b273866c/addons/payment/models/account_payment.py#L13-L21 and for draft payments only. https://github.com/odoo/odoo/blob/43fccd7aaa83117c95babc52d60dd1c26b28335a/addons/payment/views/account_payment_views.xml#L16 Before this change the form view will fail when partner_id has a company that is not in the context. This is not incorrect, but it is unexpected as `related_partner_ids` is not needed to just show the form view. A way to reproduce the issue is to confirm a payment, then change the partner company to a company not accessible for current user. This causes issues during migrations: the form view for the failing payments is displayed just fine for versions <=13.0 closes odoo/odoo#98623 X-original-commit: a126f007573a41d22108d9d7887f92b6926ef3ec Signed-off-by: William André (wan) <wan@odoo.com> Signed-off-by: Alvaro Fuentes Suarez (afu) <afu@odoo.com>
