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.

Monitoring a virtual user during RPT schedule execution- This is a demonstration of setting up the monitoring of a virtual user during schedule execution in IBM Rational Performance Tester (RPT) V8.6. This is helpful if you want to check on the status of a virtual user independent of the result of the entire schedule execution. You can find more information about this activity in the Rational Performance Tester docu

The Rational Test Workbench family of products includes
These products have optional components and sometimes it's hard to figure out which package to down load to get everything needed for one of the products.
The components are available individually but they're also bundled into three offerings
RTW (Rational Test Workbench) Offering contains
RPTS (Rational Performance Test Server) Offering contains
RTVS (Rational Test Virtualization Server) Offering contains
Note that some of the individual products are available in two different offerings. In addition some of the optional components for a product requires obtaining two of the three offerings.
For example, to get Rational Performance Tester you'll want the Rational Test Workbench Offering and then the Rational Performance Tester Agent from either the RPTS or RTVS offering.
The complete set of four components for Rational Integration Tester are:
1. Rational Integration Tester (RIT)
2. Rational Integration Tester Agent (RITA)
3. Rational Integration Tester Platform Pack (RITPP)
4. Rational Tester Control Panel (RTCP)
It doesn't matter which offerings these components are obtained, as long as you get all four of them. For Rational Integration Tester customers I usually recommend getting the Rational Test Workbench offering which includes RIT, RITPP, RTCP, and then either the RPTS or RTVS component to get the Rational Integration Tester Agent.
