As for the disabling of inventory status, we should have to taken the necessary steps to delete all dependent records assigned to the non-default status before disabling the feature.
Or if there are items assigned to the non-default status, these items will have to be changed from the non-default status to the default status and then proceed in deleting the non-default statuses.
Non-default statuses will have to be deleted first in order to disable the Inventory Status feature.
To disable the Inventory Status,
- Navigating to Setup > Company > Enable Features
- Under the Items & Inventory tab, unmark the Inventory Status box
- Click Save
