Stock Removal Location by Priority

This module lets you rank your storage locations so that Odoo decides which stock to take first when several locations hold the same product with the same incoming date.

• In Inventory settings a new "Removal Priority" option can be enabled. Once enabled, a "Removal Priority" field becomes visible on the location form, next to the existing removal strategy. New locations start with a default priority of 10.
• The priority is copied onto the stock quantities stored in each location, so it can be used when Odoo searches for stock to reserve.
• When the option is active, the order in which stock is picked changes: for FIFO (oldest first) Odoo still looks at the incoming date first, then at the location priority, then at the record order; for LIFO (newest first) it looks at the incoming date in reverse, then at the location priority, then at the record order. Lower priority numbers are taken before higher ones.
• If a removal strategy other than FIFO or LIFO is used while the option is active, Odoo stops with an error saying that strategy is not implemented.
• When the option is not enabled, Odoo behaves exactly as before.

The module touches stock.location, stock.quant and the Inventory settings screen (res.config.settings).
