Hello, I'm encountering an issue with the purchase module in Odoo. Whenever we make a request for quotation and modify anything in the order lines, the expected delivery date shifts automatically. This often leads to us sending out emails with incorrect delivery dates. Currently, we manually type the correct delivery date in emails, but this approach is not only time-consuming but also results in data inconsistencies. Ideally, I would like to have the option to select an expected delivery date initially and then set a fixed delivery date, without it changing automatically or being modified by the supplier. In our case, most suppliers confirm delivery dates via email rather than through our system. I'm looking for a solution to prevent the delivery date from changing automatically. Any advice on how to address this would be greatly appreciated.
