• What is the cause and solution for SAP error message SUSR_CERT112 - Alias does not exist ?

  The SAP error message SUSR_CERT112: Alias does not exist typically occurs when there is an issue with the digital certificate or key alias in the SAP system. This error is often related to the use of Secure Network Communications (SNC) or when trying to access a secure connection that requires a valid certificate.
  Cause:
  
  Missing Alias: The specified alias for the certificate does not exist in the keystore.
  Incorrect Configuration: The configuration for the SNC or the SSL connection may be incorrect, leading to the system not being able to find the required alias.
  Keystore Issues: The keystore may not be properly set up or may not contain the necessary certificates.
  Expired Certificates: The certificate associated with the alias may have expired or been deleted.
  
  Solution:
  
  
  Check Keystore: Verify that the keystore is correctly configured and that the alias in question exists. You can use the SAP transaction STRUST to manage and view the certificates and their aliases.
  
  
  Add Missing Alias: If the alias does not exist, you may need to create it. This can be done by importing the necessary certificate into the keystore using the STRUST transaction.
  
  
  Verify Configuration: Ensure that the SNC or SSL configuration is correct. Check the parameters in the instance profile or the relevant configuration settings in the SAP system.
  
  
  Check Certificate Validity: If the alias exists but the certificate is expired, you will need to renew the certificate and update the keystore accordingly.
