Stock Picking Restrict Cancel with Original Moves

This module gives warehouse managers a safety switch on each operation type (for example Receipts, Delivery Orders, Internal Transfers). On the operation type form, right after the backorder setting, a new checkbox called "Restrict Cancellation with Original Moves" can be turned on.

When that checkbox is active, Odoo checks the chain of moves before cancelling. If a move in the transfer has a previous move that is still waiting, ready or assigned (not done and not cancelled), the cancellation is refused and an error message is shown. The message lists the blocking documents, for example the pickings that still need to be completed.

• The check is applied per operation type, so it can be enabled only where needed.
• Cancellation is still allowed when all previous moves are already done or cancelled, or when the previous moves are part of the same cancellation request.
• Internal operations such as merging moves are not blocked by this rule.

The module extends stock.move and stock.picking.type and adds a field to the operation type form. It does not create new menus or reports.
