  The SAP error message SUSR_CERT023: No certificate is available typically occurs when the system is unable to find a required digital certificate for a user or a specific operation. This can happen in various contexts, such as when using Secure Network Communications (SNC), Single Sign-On (SSO), or when dealing with secure communications in general.
  Causes:
  
  Missing User Certificate: The user does not have a valid digital certificate assigned in the system.
  Expired Certificate: The certificate that was previously assigned has expired and is no longer valid.
  Incorrect Configuration: The system may not be properly configured to recognize or use the certificates.
  Profile Issues: The user profile may not be set up correctly to include the necessary certificate information.
  Transport Layer Security (TLS) Issues: If the system is using TLS, there may be issues with the certificate chain or trust relationships.

  Check User Certificates:
  
  Go to transaction SU01 (User Maintenance) and check the user’s certificate settings.
  Ensure that the user has a valid certificate assigned.

  Ensure that the system is configured to use the correct certificate store.
  
  
  
  Check Profile Settings:
