Configuration changes you make in AMC are saved, but they are not in effect until you apply them, as described in Applying Configuration Changes. You can use the policy audit log file to find out what changes are pending, and go to the Apply changes page in AMC to discard them. Pending changes can only be discarded as a group: you cannot discard them selectively.
To discard pending changes
(Optional) You can review the list of pending changes in the management console audit log file.
See Management Audit Log for more information.
Click Pending changes in the upper right of any page in the AMC.
The Apply Pending Changes dialog displays.
On the Apply Changes page, click Discard.
The changes are discarded.
