• What is the cause and solution for SAP error message SRT_WSP2584 - Key hash '&1' (usage '&2') not unique. Use key version instead. ?

  The SAP error message SRT_WSP2584 indicates that there is a problem with the uniqueness of a key hash in the context of web service communication. This error typically arises in scenarios involving SAP's web service runtime, particularly when dealing with web service proxies or service definitions.
  Cause:
  The error message states that the key hash (represented by &1) for a specific usage (represented by &2) is not unique. This can occur due to several reasons:
  
  
  Duplicate Entries: There may be multiple entries in the service registry or configuration that share the same key hash and usage, leading to ambiguity in identifying the correct service.
  
  
  Configuration Issues: Incorrect or incomplete configuration of web service definitions or proxies can lead to conflicts in key hashes.
  
  
  Versioning Conflicts: If multiple versions of a service are deployed and they share the same key hash, the system may not be able to distinguish between them.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Service Registry: Review the service registry or the relevant configuration in the SAP system to identify any duplicate entries. Ensure that each service has a unique key hash.
  
  
  Adjust Configuration: If duplicates are found, adjust the configuration to ensure that each service definition or proxy has a unique key hash. This may involve renaming or reconfiguring services.
  
  
  Use Key Version: As suggested by the error message, you can opt to use the key version instead of the key hash. This may involve modifying the service call or configuration to specify the version explicitly.
  
  
  Clear Cache: Sometimes, clearing the cache of the web service runtime can help resolve issues related to stale or outdated configurations.
  
  
  Consult Documentation: Refer to SAP documentation or support notes related to web service configuration and error handling for additional guidance.
  
  
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance, especially if this is a production environment.
