When a change is made directly into a table, there might be cases where saving isn't possible. This tip explains the reasons and the possible actions to take in such cases.
Background
SQL Server Management Studio is a powerful tool which can allow accessing and changing database even if they are currently used. In many cases, you will be the one using the database, as part of an ongoing development so there is no risk recreating tables or even deleting data. In such case, you can avoid such error messages each time you want to make a change.

How To Avoid It
Go to Settings. Then go to Designers. You will see the "Prevent saving changes that require table re-creation" setting checked. Uncheck it and press OK.
