The Summary report provides a detailed cost report that can be used as a invoice detail specification. The way you've defined your Services, determines what you'll see here.
Once you've logged into the system, go to "Reports" > 'Summary'. From here you're able to generate different kinds of detailed costs reports, which can be used for billing, charge back and show back.
Once you have selected your date range and Report, you can start viewing your summary cost report. By default it will show all consumed services for this Report, grouped account, considering the selected 'Depth'. Therefore it is important that you select an appropriate 'Depth' when running this report.
The Summary report has a few reporting options that you can turn on and off. These options allow you to create more or less detailed textual representations of your data:
If you want to include a detailed grouping of Services and Service Categories, then you'll need to have the Services checkbox enabled. The same goes for including Instance level information. The latter enables you to view resource level consumption data, such as the Virtual Machine, Container or User Name.
