Negative scalable quantity in Magento 2 can occur due to inventory mismanagement, concurrent orders, custom code or extensions, database inconsistencies, or configuration issues.


Here are a few possibilities:

  • Incorrect configuration: If there are misconfigurations or incorrect settings in your Magento 2 store's inventory management, it could potentially result in negative scalable quantities. For example, if the system is not properly tracking inventory adjustments or if there are conflicts with the inventory management settings, it may lead to negative values.
  • Manual adjustments: If someone manually adjusts the scalable quantity of a product and enters a negative value by mistake, it can cause the quantity to become negative. This could happen when making inventory adjustments directly in the Magento admin panel or through API calls.
  • Customizations or extensions: If you have customizations or third-party extensions installed in your Magento 2 store that interact with the inventory management system, they could introduce bugs or errors that cause negative scalable quantities.

To troubleshoot the issue and prevent negative scalable quantities, consider the following steps:

  • Review your inventory management configuration and ensure that all settings are properly configured.

  • Check for any customizations or extensions that might be interfering with the inventory management functionality. Disable or temporarily remove them to see if the issue persists.

  • Monitor any manual inventory adjustments made and ensure that negative values are not entered accidentally.

  • Stay up-to-date with Magento 2 updates and patches, as they often include bug fixes and improvements related to inventory management.
