I already generated EWA report and I got the following result:
1. Performance Overview PRD
The performance of your system was analyzed with respect to average response times and total workload. We have detected some problems that may impair system performance.
To ensure adequate performance in your core business transactions, you should take corrective action as soon as possible. For further information, please SAP Support.
Rating Check
Performance Evaluation
The following table shows the average response times for various task types:
Task type Dialog Steps Avg. Resp. Time in ms Avg. CPU Time in ms Avg. Wait Time in ms Avg. Load Time in ms Avg. DB Time in ms Avg. GUI Time in ms

SPOOL 9989 1686.8 37.1 55.6 0.3 49.2 0.0
1.1. Current Workload
The following table lists the number of current users (measured from our workload analysis) in your system.
Users Low Activity Medium Activity High Activity Total Users
Measured in System 162 119 6 287
1.2. Performance Evaluation
The measured times are compared against reference times to provide a rating.
- If the number of dialog steps in an hour is less than 1000 this hour is not considered.
- If the total number of transaction steps is less than 24000, the rating for the task is not performed and a blue line is entered in the table.
The table below shows that a performance problem is expected for the task that is rated YELLOW.

The ratings in the table above are determined by comparisons against the reference table below.
If the dialog response times are very poor, it will cause a RED rating for the entire check.

1.3. Transaction Profile Check
The following tables show the response times and the number of dialog steps for the transactions that cause the highest workload in your system. NOTE: A business transaction normally consists of more than one dialog step. As a rough estimate, the actual number of business transactions that are executed in your system is approximately one third of the total dialog steps shown. (Transaction CPIC/RFC is not taken into account.)
1.3.1. Transactions by Total Workload
The following tables list the activities with the highest contribution to the total workload.

0.6% of the "Total Resp. Time" in the above table is caused by customer transactions.
According to our analysis, the main system load is caused by background jobs.
The EarlyWatch Alert Service can only detect performance problems for dialog, update and RFC response times. This service does not evaluate performance problems for background jobs.
1.3.2. Transactions by DB Load
The following transaction profiles list the transactions that have the greatest share in the database load, sorted by percentage of total database access times.
