While working on a specific scenario, I noticed three different playbacks had three different Page element status codes.
Below was my observation after analyzing the playback data
The Page Element Status code was 100% successful for the first run –
A bar chart that shows the following information to indicate the overall success of the run.
Here, the page element success means that the response code verification point passed for that request. If a request has no verification points, success means that the server received the request and returned a response with a status code in the 200 or 300 category or returned an expected response with a status code in the 400 or 500 category.
Here, if you notice the section ‘Server Health Summary’, the number of total page element attempts is equal to the total page element Status code success. Hence we see success rate for Page Element Status code is 100%
The Page Element Status code was 99.26% successful for the second run -
Notice the section ‘Server Health Summary’, the number of total page element attempts is NOT equal to the total page element Status code success. Hence we see success rate for Page Element Status code is 99.26%
The Page Element Status code was 84.44% successful for the third run -
Notice the section ‘Server Health Summary’, the number of total page element attempts is NOT equal to the total page element Status code success. Hence we see success rate for Page Element Status code is 84.44%

When establishing the stages of execution in a schedule, you may want to pull down the active virtual users at different intervals but may not find an option to do that in Rational Performance Tester (RPT).
You may also find the below Request for Enhancement (RFE) whose status may say the feature is delivered -
However, the RFE had been closed saying that the functionality was already available in the product.
The explanation is that "Change Rate" could mean "Ramp Up" rate or "Ramp Down" rate depending on the context.
If the current stage has more users than the previous one, "change rate" means "Ramp Up" and if it has lesser users it will mean "Ramp Down",
For example, the first stage may have 100 users and the second stage have just 1 user. The "Ramp Down" happens in the second stage.

Socket recording script correlation in Rational Performance Tester (RPT):
In RPT, the script which is recorded using socket recording do not contain information in request and response format. The recorded script is in send and receive format. Information recorded in the send and receive format is basic in nature, meaning the information is either in binary, ASCII or Hex.
Correlation of these values manually is difficult. The binary data need to be converted to ASCII format before the correlation is performed. Dynamic values are dependent on both the application type and the encoding format used in the application. Hence the correlation in binary format is not done.
Correlation of ASCII format is handled like normal manual correlation.
. The value is searched in the reponse content of the receive message.
. A reference is created, for the ASCII value.
. This is replaced in the send requests in the script.
Sometimes, hex codes are also considered for correlation. Here the hex codes in the receive format are manually converted to ASCII format and the relevant values are considered for reference. Once the reference is created, this is replaced in the send request, as done in ASCII format.
This topic covers the basic of correlation of scripts recorded using socket protocol, using RPT.

First, make sure to have gone through the prerequisites for SAP testing. Refer the below link -
As you see in the link, you can have a maximum of only 50 virtual users on an agent for a SAP GUI test.
Beyond that, failures such as "connection errors", "SAP GUI Component not found" and "Invalid arguments" will start occurring during playback.
This is a result of how SAP has implemented the test automation API in SAP GUI.
Depending upon the script's complexity and the number of GUI components that are part of the script's scenario, it is likely that a script can be played back for only a lesser number of users. These limitations arise out of the SAP automation framework and not Rational Performance Tester (RPT) tool itself. The limitation holds good for other testing tools as well.
Since the limitation is on the on number of users per engine Java process, I tried setting up multiple agent engines in the same physical machine. This involved creation of multiple host aliases in the agent machine and then adding those hosts as locations to be used in user groups (Vertically Scaling an agent machine).
I personally saw that high capacity machine with multiple Agents did not resolve the issue.
Below are some recommendations while load testing a SAP GUI

It''s becoming more and more common for secure websites to use stronger encryption. That's fine but when recording SSL traffic with Rational Performance Tester that stronger encryption level can prevent RPT from recording traffic from that site.
The solution is to install java policy files that allow use of the stronger encryption methods. This is explained in the the technote Enab
I'll walk you through the steps. The technote would have you start with step 1. But you can start with step 4.
