Standard Odoo scrap handles one product per order. This module adds an Operations tab so warehouse staff can list several products, quantities, and tracking details on a single scrap document and validate them together. Header product fields are hidden in favour of the line list, while replenish options and scrap reason tags stay on the form as usual.

Multiple Lines

Add as many products as needed on one scrap order instead of creating separate documents for each item. Use Add a Product on the Operations tab to build the list.

Per-Line Tracking

Each line supports its own lot or serial number, package, owner, and unit of measure. Lot-tracked products show the Lot/Serial column when tracking is enabled.

One-Click Validate

Validate once to generate stock moves for every line on the scrap order. The document moves to Done and product moves are available from the smart button.

Open Scrap from Inventory

Go to Inventory → Operations → Scrap and create a new scrap order. Set the source location (for example WH/Stock) and scrap location as usual. The Operations tab is ready for line entry while replenish and scrap reason fields remain on the header.

Add products on Operations

Use the Operations tab to add products, quantities, and optional lot/serial numbers. Mix storable products on the same order — for example several units of one SKU plus a lot-tracked line with its serial or lot reference.

Validate all lines together

Click Validate to post stock moves for every line. The scrap reference is assigned, the status becomes Done, and you can open Product Moves to review the generated stock transactions.
