• What is the cause and solution for SAP error message STRUSTCR018 - Issuer &1 already exists in the source list ?

  The SAP error message STRUSTCR018 indicates that there is an issue with the SSL (Secure Sockets Layer) configuration in the SAP system, specifically related to the SSL server PSE (Personal Security Environment). The message states that the issuer you are trying to add already exists in the source list.

  Review the list of existing certificates to see if the issuer you are trying to add is already present.
  
  
  
  Remove or Replace Existing Certificate:
  
  If the existing certificate is outdated or incorrect, you may choose to delete it. To do this, select the certificate and use the delete option.

  Import the New Certificate:

  Use the "Import Certificate" option in the STRUST transaction to add the new certificate.
  
  
  
  Save Changes:
