Performance information displayed in this tab can be used to identify and analyze the cause of a performance problem and serves as the main source of input for future tuning decisions. Use the Activity tab to analyze various aspects of your SAP system’s system's activities. For example:
- Check which organization had the highest average response time.
- Check the average response time of a user over time and observe the elements that constitute his response time.
- View the overtime SLA compliance of a transaction.
- View an over time graph that displays the number of steps executed with respect to their average response time.
- Determine which transactions in your system experienced the highest response time.
...
The Main area shows comprehensive information on the selected entity. You can choose from several views in the Main area to examine the entity from different angles. You can, for example, focus exclusively on your system’s system's Performance data (default), or SLA Compliance, over the selected time period.
...
For example, when you want to drill down to an associated entity, such as a specific organization, to view additional information, choose Locales from the Association controls. Note that the Tab heading and the Main area remain unchanged. Click the row of the locale entity you want to view detailed information for. The Tab heading indicates the newly selected entity; the Main area displays information on the locale you drilled down to, and the Association area shows information on the applications associated with selected locale. See “About About Precise for SAP tabs” on page 12, “How tabs, How most tabs are structured” on page 13structured, and “Tasks Tasks common to all tabs” on page 17tabs.

RFC Entities in the Main Area

When performing a tuning audit it is very important to analyze and understand the performance behavior of your SAP system. You may have already drilled down to analyze the performance of a single organization, locale or application. However, examining the entire SAP system’s system's behavior can alert you to the health of your system. This will help you answer questions such as: "A specific transaction suffers from long database times, but is the entire SAP system suffering from long database time?"
...
When you analyze and tune the performance of an application component (such as, Organization, Locale and Application) it is important to take into consideration its performance over time. Precise for SAP allows you easily view the component’s component's performance over a selected time period.
You study a component’s component's performance over time for the following reasons:
...
Applications are called upon to support additional users and data, over the years. One of today’s tasks is ensure that your application and servers are scalable for tomorrow’s tomorrow's tasks.
Precise for SAP enables you to determine if your SAP system is scalable. This is done by examining the impact of the number of transactions, steps and RFC calls on the average response time. In a well-scalable SAP system, growth in the number of transactions, steps and RFC calls will not impact the average response time. This can be observed in the Scalability View in the Steps and Response Time (Avg) graph.
