Purchase Planned Date Container Deposit

This module is a small bridge between two purchase features: setting the planned date manually on a purchase order, and automatically adding container deposit lines when you buy products that come in returnable packaging.

When Odoo builds a deposit container line for a product and quantity, this module checks whether the purchase order already has a planned date. If it does, that same planned date is copied onto the new deposit line. Without this, the deposit line could end up with a different or empty planned date.

• It only changes the purchase.order model.
• It extends the method that prepares deposit container line values.
• The rule is simple: if the order has a planned date, the deposit line uses it.
• It installs automatically because it depends on both related modules.

There are no new menus, screens, buttons, reports, emails or scheduled jobs in this module. Users will not see a new screen; they will simply notice that deposit lines follow the planned date they entered on the purchase order. This keeps delivery and receipt planning consistent for products sold with returnable containers.
