If you want to understand patterns you're seeing in your data, run a detail report. With it, you can get more details about your telecom use and costs. (If you want to see high-level trends, view a view a standard summary billing report or create a custom summary billing report.)
You can edit any of the reports or create a custom detail billing report to better suit your needs. By default, when you run a summary or detail report, Hosted Bill Analyst tries to extract data from every account you have permission to, which increases processing time and creates bigger reports. If you want to see a report immediately (and not wait for an order to be processed), you can reduce the number of records it contains by using the hierarchy/level feature or creating a filter to search for specific service IDs and account numbers.
