• What is the cause and solution for SAP error message /SRMSMC/SUSTAIN018 - Expiration date of the default QM system certificate is in the past ?

  The SAP error message /SRMSMC/SUSTAIN018 indicates that the expiration date of the default Quality Management (QM) system certificate has passed. This typically occurs in systems that utilize secure communication protocols, such as SSL/TLS, where certificates are used to establish secure connections.
  Cause:
  
  Expired Certificate: The primary cause of this error is that the certificate used for secure communication has expired. Certificates have a validity period, and once this period is over, the system will not accept the certificate for secure connections.
  Configuration Issues: Sometimes, the system may be configured to use a specific certificate that is no longer valid or has not been updated.
  
  Solution:
  To resolve this issue, you will need to update or replace the expired certificate. Here are the steps to do so:
  
  
  Identify the Expired Certificate:
  
  Use transaction code STRUST in the SAP GUI to access the Trust Manager.
  Check the SSL Client (Standard) or SSL Server (Standard) entries to find the expired certificate.
  
  
  
  Obtain a New Certificate:
  
  If you are using a self-signed certificate, you can generate a new one.
  If you are using a certificate from a Certificate Authority (CA), you will need to request a new certificate from the CA.
  
  
  
  Import the New Certificate:
  
  In the Trust Manager (STRUST), you can import the new certificate.
  If you generated a self-signed certificate, you can create it directly in the Trust Manager.
  
  
  
  Assign the New Certificate:
  
  Ensure that the new certificate is assigned to the appropriate SSL configuration (e.g., SSL Client or SSL Server).
  
  
  
  Restart the SAP Services:
  
  After updating the certificate, restart the relevant SAP services to ensure that the changes take effect.
  
  
  
  Test the Connection:
  
  After the new certificate is in place, test the connection to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Certificate Management: Regularly monitor and manage certificates to avoid expiration issues. Implement a process for renewing certificates before they expire.
  Documentation: Refer to SAP documentation on SSL configuration and certificate management for detailed steps and best practices.
  Security Considerations: Ensure that the new certificates are securely stored and managed to maintain the integrity of your system's security.
  
  By following these steps, you should be able to resolve the /SRMSMC/SUSTAIN018 error and restore secure communication in your SAP system.
