• What is the cause and solution for SAP error message 1S426 - PSE already exists ?

  The SAP error message 1S426: PSE already exists typically occurs when you are trying to create a new Personal Security Environment (PSE) in SAP, but a PSE with the same name or identifier already exists in the system. This can happen during various operations, such as when configuring SSL or setting up secure communication.
  Cause:
  
  Existing PSE: The most common cause is that a PSE with the same name already exists in the system.
  Incorrect Configuration: There may be a misconfiguration in the system that leads to the attempt to create a duplicate PSE.
  System Migration or Upgrade: If the system has been migrated or upgraded, existing PSEs may not have been properly handled.
  
  Solution:
  
  
  Check Existing PSEs:
  
  Use transaction code STRUST to check the existing PSEs in the system. Look for the PSE you are trying to create and verify its details.
  
  
  
  Delete or Rename:
  
  If the existing PSE is not needed, you can delete it. Be cautious with this step, as it may affect existing configurations.
  Alternatively, if you need to keep the existing PSE, consider renaming the new PSE you are trying to create.
  
  
  
  Use the Correct PSE:
  
  If you are trying to configure SSL or secure communication, ensure you are using the correct PSE that is already configured for your purpose.
  
  
  
  Check for Multiple Instances:
  
  If you have multiple instances of SAP or multiple clients, ensure you are not trying to create a PSE in the wrong instance or client.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to PSE management for specific guidance on your version of SAP.
