In Odoo, when you scrap a product, it should be moved from your available stock to a virtual scrap location. If scrapped units are still appearing as available in your stock, it could be due to a few reasons:

- Customizations or Third-Party Apps: Check if anyone has customized Odoo or installed any third-party apps that might be affecting the stock levels.

- Scrap Location Type: Ensure that the location type of the scrap location hasn’t been changed.

- Filters: The standard behavior is to exclude scrapped quantity unless you click through the Quantity on Hand button and remove the On Hand filter.

If you’ve checked all of these and the issue persists, you might need to revisit how you’re managing scrap in Odoo. Here’s a brief overview of how to manage scrap in Odoo:

1. Enable Storage Locations: Go to Configuration > Settings and enable Storage Locations.

2. Create a Scrap Location: Go to Configuration > Locations and create a new location. Set the Location Type to Inventory Loss and enable the “Is a Scrap Location?” option.

3. Scrap Products: When a product is identified as scrap, move it to the scrap location. This should trigger an adjustment in the inventory.

Remember to replace the placeholders in the steps with your actual data.
