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.

 | Click on the Details icon to open a dialog box that enables you to view additional details for the selected step. |
| Time | Displays the time unit the transaction was run in. |
| Transaction | Displays the name of the transaction that was run. |
| User | Indicates the user that initiated the transaction. |
| Client | Displays the user's client. |
| Program | Displays the name of the program that was run. |
| Screen | Displays the screen that was run. |
| GUI Program | Displays the GUI program that was run. |
| Response Time | Displays the total activity time. The response time is the sum of the client time, the queue time, the application time, and the database time. |
| Backend Response Team | Displays the total Back End activity time. The Backend Response Time is the sum of the queue time, the application time, and the database time. |
| Steps | Number of steps running for the transaction, user, client, program, screen and GUI program, during the specified time slice. |
| Client Time | Displays the total client time of the activity. The client time is the time the activity spent going to or from the SAP application server plus the time it spent in the client machine. |
| Queue Time | Displays the total queue time of the activity. The queue time is the time the activity spent in the SAP application server waiting for a work process to process it. |
| Application Time | Displays the total application time of the activity. The application time is the time the activity spent being processed by the SAP application server. |
| DB Time | Displays the total database time of the activity. The database time is the time the activity spent in the SAP database. |

- Overview. Displays the entity’s most important counters, in addition to the SLA compliance pie chart and a pie chart representing the various components of response time. The response time components include:
- Client time
- Queue time
- Application time
- Database time
- Performance. Displays the average response time for the entity over the selected time period, broken down into the following components:
- Client time
- Queue time
- Application time
- Database time
- Load. Displays the number of transactions and steps executed by the selected entity and its summed response time broken down into its components.
- SLA compliance. Displays SLA compliance over the selected time period.
- Scalability. Displays the steps and the average response time over the selected time period.

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.
