• What is the cause and solution for SAP error message SIPT105 - Serial number of the encryption certificate is &1 instead of &2 ?

  The SAP error message SIPT105 indicates a mismatch in the serial number of an encryption certificate. Specifically, it means that the system expected a certificate with a specific serial number (denoted as &2), but instead found a certificate with a different serial number (denoted as &1).
  Cause:
  
  
  Certificate Mismatch: The most common cause of this error is that the encryption certificate being used does not match the expected certificate. This can happen if:
  
  The wrong certificate was installed or configured.
  The certificate has been replaced or updated, but the system has not been properly configured to recognize the new certificate.
  There are multiple certificates in use, and the system is referencing the wrong one.
  
  
  
  Configuration Issues: There may be issues in the configuration settings related to the encryption or the certificate management in the SAP system.
  
  
  Solution:
  
  
  Verify the Certificate:
  
  Check the installed encryption certificate and its serial number. You can do this by accessing the certificate store in the SAP system.
  Compare the serial number of the installed certificate with the expected serial number (the one indicated in the error message).
  
  
  
  Update the Certificate:
  
  If the installed certificate is incorrect, you may need to install the correct certificate that matches the expected serial number.
  If the certificate has been updated, ensure that the new certificate is properly configured in the SAP system.
  
  
  
  Configuration Check:
  
  Review the configuration settings related to the encryption and certificates in the SAP system. Ensure that all settings are correctly pointing to the right certificate.
  Check transaction codes like STRUST (for managing SSL certificates) to ensure that the correct certificates are in place.
  
  
  
  Restart Services:
  
  After making changes to the certificates or configurations, it may be necessary to restart the relevant services or the entire SAP system to ensure that the changes take effect.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support notes related to certificate management and encryption to ensure compliance with best practices.
