• What is the cause and solution for SAP error message STRUSTCR036 - CRL of issuer &1 is available ?

  The SAP error message STRUSTCR036 indicates that a Certificate Revocation List (CRL) for a specific issuer is available. This message typically arises in the context of SSL/TLS communication or when dealing with digital certificates in SAP systems.
  Cause:
  The error message STRUSTCR036 is generally triggered when the system detects that a CRL for a certificate issuer is available. This means that the system has access to a list of certificates that have been revoked by the issuer, which is an important aspect of maintaining secure communications. The presence of a CRL is a good sign, as it indicates that the system is checking for the validity of certificates.
  Solution:
  
  
  Check CRL Configuration: Ensure that the CRL is correctly configured in the SAP Trust Manager (transaction STRUST). You can do this by:
  
  Navigating to transaction STRUST.
  Selecting the appropriate SSL server or client SSL configuration.
  Checking the "CRL" tab to see if the CRL is correctly loaded and up to date.
  
  
  
  Update CRL: If the CRL is outdated or not properly loaded, you may need to update it. You can do this by:
  
  Downloading the latest CRL from the Certificate Authority (CA) that issued the certificates.
  Importing the updated CRL into the SAP system using the Trust Manager.
  
  
  
  Verify Certificate Chain: Ensure that the entire certificate chain is valid and that all intermediate certificates are also trusted and available in the system.
  
  
  Check Network Connectivity: Ensure that the SAP system can reach the CRL distribution point specified in the certificate. If the system cannot access the CRL, it may lead to issues with certificate validation.
  
  
  Review Logs: Check the SAP system logs for any additional error messages or warnings that may provide more context about the issue.
  
  
  Consult Documentation: Refer to SAP documentation or support notes related to SSL/TLS configuration and certificate management for further guidance.
  
  
  Related Information:
  
  Transaction STRUST: This is the SAP transaction used for managing SSL certificates and trust relationships.
  Certificate Authorities (CAs): Understanding the role of CAs in issuing and revoking certificates is crucial for managing SSL/TLS communications.
  CRL Distribution Points: Certificates often contain information about where to find the CRL. Ensure that these points are accessible from your SAP system.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to CRLs and SSL configurations.
  
  By following these steps, you should be able to resolve the STRUSTCR036 error and ensure that your SAP system is properly configured for secure communications.
