When you make a change to your decision within any decision screen, this change is automatically saved by clicking the Apply button:
The Apply button will be grey and won’t be able to be clicked until you make a change to your decisions.
There is no Submit Decisions or Save All Decisions button. The decisions you see on-screen will be those that process at the Rollover.
If you would like to double check if your saved decisions, view the Current Decisions Report available under the Key Reports menu.
