Account Invoice Check Picking Date

This module adds a control when you post a vendor bill that is linked to stock moves (for example, a bill created from a receipt).

• When you click Post on a vendor bill, Odoo looks at the stock moves connected to that invoice and finds the earliest and latest move dates.
• If the month of the invoice accounting date is different from the month of the latest stock move, posting is stopped and a popup opens with the message "Accounting date does not match with stock move dates".
• The popup shows the accounting date, the first stock move date and the last stock move date, so you can see the mismatch.
• The popup has a Continue button that is only visible to users with accounting manager rights. Pressing it posts the invoice anyway.
• A Cancel button closes the popup without posting.

The check applies by default to vendor bills (in_invoice). The list of invoice types to check can be changed through a system parameter, but the code only reads it; no screen is provided to edit it.

The module extends account.move and adds a new wizard model, invoice.picking.date.check.wiz, used only for the warning popup. It depends on stock_account.
