Let’s take a tour by exploring the setup of Stock status.
These Stock statuses can be used to manage the customer order status. Each Stock status can be individually disabled, by editing them. The Stock status can be deleted as well.
Note: The only issue with the deletion of a Stock status is that the Stock status information will be deleted with it.
You can edit the Stock status by clicking the edit pencil button.
Checking an individual box in the first column will select the Stock status within the same row. Once selected, you can choose to "delete" the Stock status on the top left corner and click the + button to add new.
Then product stock list will be available on Product add/edit --> Data tab ---> Stock status list, There you can choose the status of stock
