Clicking the Save button in any particular portion of the WAVE 3000 Server interface results in immediate validation of the changes to that section.

If valid, the system saves your changes to a temporary location and notifies you in the yellow box at the top of the screen that you have changes pending. These changes are not yet active, and do not effect users, or the system, until you click Commit Changes.
Clicking the Commit Changes button results in the validation of all pending changes.

If a change is invalid, or a requirement for the change has not yet been met, then the yellow box at the top of the screen notifies you of the error. Correct the error and click Commit Changes again. Repeat this process until all errors have been corrected. Changes are not applied (activated) until all errors have been eliminated.
