• What is the cause and solution for SAP error message SRT_WSP3153 - System &1 has same system key as system &2 that is already registered ?

  The SAP error message SRT_WSP3153 indicates that there is a conflict in the system registration for web service communication. Specifically, it means that two systems are trying to register with the same system key, which is not allowed. This can happen in scenarios where multiple systems are configured to communicate with each other using SAP's web service infrastructure.
  Cause:
  
  Duplicate System Registration: The error typically arises when two different systems (e.g., different instances of SAP) are configured to use the same system key in the SAP Web Service Runtime (WSR).
  Configuration Issues: This can occur due to incorrect configuration settings in the SAP system landscape, where the same system key is inadvertently assigned to multiple systems.
  Transport Issues: If transport requests are not properly managed, it can lead to duplicate entries in the system registry.
  
  Solution:
  To resolve this issue, you can follow these steps:
  
  
  Identify the Systems: Determine which systems are involved in the conflict. The error message provides the system keys for both systems (e.g., &1 and &2). Check the configuration of both systems.
  
  
  Check System Keys: 
  
  Go to the transaction SOAMANAGER in both systems.
  Navigate to the Web Service Configuration section.
  Check the system keys assigned to each system and ensure they are unique.
  
  
  
  Change System Key: If you find that two systems are using the same system key:
  
  Change the system key for one of the systems to a unique value.
  Ensure that the new key is properly configured in all relevant settings.
  
  
  
  Delete Duplicate Entries: If there are duplicate entries in the system registry:
  
  Use transaction SICF to check the service definitions.
  Remove or deactivate the duplicate service definitions.
  
  
  
  Transport Management: If the issue arose due to transport requests, ensure that the transport management is correctly set up to avoid conflicts in system keys.
  
  
  Restart Services: After making changes, restart the relevant services or the entire system to ensure that the changes take effect.
