Requiring Revision Comments

Administrators can force users to supply a check-in reason, however, by adjusting the properties for the project. This requirement will apply no matter which way users perform the check-in.

Choose Project > Properties .

The Project Properties dialog box opens.
Click the Options tab.
Check Require Revision Comment When Files are Checked In.
Note: This check box applies only to the application, not to integrations.
Click OK.

From this time on, the Check-in dialog box will always open when users check in files, and they will need to type text in the Reason for Check-in field before completing the operation.
