Saving changes after database table design is not allowed

After you modify the table design for a SQL Server 2012 database, the following error message appears when you save the table design:

Saving changes is not allowed. Your changes require that the following tables be deleted and recreated. You have made changes to the label that cannot be recreated or enabled the "Prevent saving changes that require table re-creation" option.

Workaround

Open tools, Options, expand Designer, Table Designer, and Database Designer,

Remove the tick before "prevent saving changes that require the table to be recreated."
