In case of RFQ with the "Ask confirmation X day(s) before" set, the email send to the vendor give a link where he (portal user) can change the date_planned of PO lines. But the change wasn't done in the server side because the `_update_date_planned` (of stock_purchase) doesn't call super if there isn't a linked move (none in case of RFQ). Call super also in case there isn't any moves. close #59040 closes odoo/odoo#63629 X-original-commit: b29ac84fd55923abf582cdee39cb32bacda3eec9 Signed-off-by: Arnold Moyaux <amoyaux@users.noreply.github.com> Signed-off-by: Rémy Voet <ryv-odoo@users.noreply.github.com>
