Control Center displays a list of all services assigned to the accounts under your enterprise ID. If you have more than 10 services, you can view the rest of your services by clicking one of the blue linked Show numbers at the top of the list or you can click the blue down arrow at the bottom of the list to add 10 services at a time to the view.
Search for the service in one of these ways:
Sort your services using the Sort by… list (e.g., Service Type). You can toggle between descending and ascending order using the arrow to the right of the Sort by… list.
Filter your services by selecting an option from the View All (Default) list.
Search for a specific service (by service type, account, etc.) using the Search by… field and search box. (To search using multiple search criteria, click Advanced Search, then fill in your search criteria and click Apply Search Filters. When you're done, click Close Advanced Search.)
When you find the service you want to work with, click the blue arrow on the right of the line for the service.
