Sql Server 'Saving changes is not permitted' error ► Prevent saving changes that require table re-creation
From Save (Not Permitted) Dialog Box on MSDN :
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.

Further explanation
By default SQL Server Management Studio prevents the dropping of tables, because when a table is dropped its data contents are lost.*
When altering a column's datatype in the table Design view, when saving the changes the database drops the table internally and then re-creates a new one.
*Your specific circumstances will not pose a consequence since your table is empty. I provide this explanation entirely to improve your understanding of the procedure.
