The message error is self explanatory :)
- Check the Allow nulls checkbox.
- Fill this column with data
- then edit the table again and uncheck the allow nulls checkbox

@amankhan: I would not upvote your question because you could have found that out by yourself. And the error is pretty self explanatory. – juergen d Aug 05 '13 at 09:38

You try to add a new column that must have a value by your definition. But you are not giving a value. Ask yourself: What should the existing records have for that column?
If you can think of a value then add this as default. If not then allow nulls for that column.

(Solve your problem) To change the Prevent saving changes that require the table re-creation option, follow these steps: 1. Open SQL Server Management Studio (SSMS). 2. On the Tools menu, click Options. 3. In the navigation pane of the Options window, click Designers. 4. Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.
Note: If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.
