ConnectWise - How can I remove unmapped statuses as choices for ARO Statuses?

If your AROs board has status IDs that you haven't mapped to an ARO status in the portal integration, you can remove them by making them inactive. 

To do so: 

1. In the ConnectWise sidebar, navigate to System -> Setup Tables. 
2. Under Category, scroll down and select Service. 
3. Click Search. 
4. Select Service Board. 
5. Find the board intended for AROs. 
6. Select the Statuses tab. 
7. Click the "Inactive" checkbox for the statuses you want to remove. If the checkbox won't let you change its status, active tickets are still using that status.
