Even though this issue first appeared in SQL Server 2008, it continues to frustrate developers using newer versions of SQL Server Management Studio (SSMS), including SSMS 19. If you've ever tried to modify a table in design mode and been blocked by the dreaded Saving changes is not permitted message, you're not alone.
Why it happens?
SSMS (SQL Server Management Studio) prevents changes that require table re-creation to avoid accidental data loss. This safeguard was introduced in SQL Server 2008 and remains enabled by default.
How to fix it?
This issue can be fixed by changing an option from the Management Studio itself.
🔹 Go to Tools → Options in SSMS.
🔹 Navigate to Designers → Select Table and Database Designers.
🔹 Uncheck "Prevent saving changes that require table re-creation" option.
Once disabled, you can freely modify your tables in design mode. Just be cautious with structural changes in production environments.
