The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.
The following actions might require a table to be re-created:
- Adding a new column to the middle of the table
- Dropping a column
- Changing column nullability
- Changing the order of the columns
- Changing the data type of a column
To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

Select Table and Database Designers: Click on "Table and Database Designers."
Uncheck "Prevent saving changes that require table re-creation": In the right-hand pane, you'll see a checkbox labeled "Prevent saving changes that require table re-creation." Uncheck this option.

Restart SSMS (if necessary): In some cases, you might need to restart SSMS for the changes to take effect.
Once you've completed these steps, SSMS will no longer prevent you from saving changes that require table re-creation. However, please be cautious when making structural changes to your database tables, especially in a production environment, as these changes can potentially lead to data loss or other unintended consequences. Always make sure to back up your data and thoroughly test any changes before applying them to a production database.
