I was trying to save a Diagram after some changes in the tables an got this error:
Saving changes is not permitted. The changes that you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created.
To Prevent this error to happen, follow this steps:
- Open SQL Server Management Studio (SSMS).
- On the Tools menu, click Options.
