Stock Barcodes GS1 Secondary Unit

This module connects the GS1 barcode reading tools with the secondary units feature. When a GS1 barcode is scanned, Odoo looks for a secondary unit whose barcode matches; if exactly one is found, it selects that secondary unit, sets the product and puts a quantity of 1 secondary unit, and converts it into the main unit quantity using the unit's conversion factor. If several secondary units match, a warning message is shown and nothing is filled.

• On product forms, a new Barcode field is added next to the secondary unit factor, so each secondary unit can store its own barcode.
• In the barcode reading screens, new fields show the secondary unit, the quantity in secondary units, and the demand/done totals in secondary units.
• The pending moves and detailed operations lists (including their kanban cards) display the secondary unit and its quantity.
• When a product is selected, its default secondary unit is proposed automatically.
• The quantity in the main unit is recalculated from the secondary quantity times the conversion factor, plus any single-unit quantity.
• Scanning a secondary unit barcode resets the lot/serial if the product changes, and the cursor jumps to the secondary quantity field.
• Logs of barcode scans now record the secondary unit and its quantity.
• When a move line is removed by the barcode process, its secondary quantity is reset to zero.
• The to-do list of pending barcode operations also shows the secondary unit and quantity.
