Error were encountered during the save process. Some database objects were not saved

Have you ever faced a situation where you wanted to modify your existing table and was bugged with following error popup.

Error were encountered during the save process. Some database objects were not saved.

  

This is because by default saving changes to the table that requires table re-creation is disabled. To fixed this issue we need to enable the option to allow save on table re-creation. Below steps explain the same.

Step 1: Open the SQL ServerManagement Studio.(Ctrl + R -> SSMS)

Step 2:  Click on the Tools tab and click on Options...link.

Step 3: This will open a popup window.  

Step 4: From the left pane expand the Designers node.Table Options screen will be displayed in the right part of window.

  

Step 5: Check the last option under Table Options section.

  

Click the OK button and save the changes. This will fix your issue.
