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

My name is Randy Simmons and I am a Rational Collaborative Lifecycle Management (CLM) Support Engineer specializing in the Requirements and Quality Management Tool. I was tasked to create a Video Series to give internal IBMer’s and external customers a basic understanding and troubleshooting options to use when Java related problems occur using the CLM suite of Tools.
This “Non-Programmer's Guide to Troubleshooting Java in CLM” video series covers the topics below. It will make you more aware of the Java Tools available for download at IBM DeveloperWorks. It give you some background about how Java and JVMs work, what data Rational Support is looking for, and the understanding of how you would go about troubleshooting Java or Performance related issues.
Click through the titles to watch the four videos, or click play on the embedded playlist at the end:
1. Introduction to Java for CLM: This video is a recording from an education session "Non-Programmer's Guide to Troubleshooting Java in CLM". This video provides an introduction to Java for IBM Rational Collaboration Lifecycle Management V5.0 users.

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
