Account EDI UBL move line uom and packaging By UNECE

This module improves the import of supplier invoices that arrive in the UBL electronic format. While importing, Odoo reads the unit code written on each invoice line and uses it to choose the right unit of measure or the right packaging for the product.

• If the code matches a packaging level defined for the product, the packaging is applied first: the packaging quantity is set to the billed quantity and the unit price is recalculated by dividing the imported price by the packaging quantity.
• If no packaging matches, Odoo looks for a unit of measure with the same UNECE code. The unit is only applied when it belongs to the same category as the product's default unit; otherwise the line is left unchanged.
• Three technical fields are stored on invoice lines: the UNECE unit code, the billed quantity and the imported unit price. They are read-only and mainly used to keep the original supplier data available during purchase reconciliation.

On the invoice form, the UNECE unit code and the imported unit price can be shown as optional columns on invoice lines for supplier invoices, so users can check what was received from the supplier. The module works together with the UBL import, unit of measure and packaging modules, and touches account.move.line and the UBL import process.
