  The SAP error message "00143 Issuer of SSO ticket is not authorized" typically occurs in the context of Single Sign-On (SSO) configurations. This error indicates that the system is unable to validate the SSO ticket because the issuer of the ticket is not recognized or authorized by the SAP system.
  Causes:
  
  Incorrect Configuration: The SSO configuration in the SAP system may not be set up correctly. This includes issues with the trust relationship between the SAP system and the identity provider (IdP).
  Missing or Incorrect Certificate: The public key certificate of the IdP may not be correctly imported into the SAP system, or it may be outdated.
  Wrong Issuer Name: The issuer name in the SSO ticket does not match the expected issuer name configured in the SAP system.
  Network Issues: There may be network issues preventing the SAP system from reaching the IdP to validate the ticket.
  Expired Ticket: The SSO ticket may have expired, leading to validation failure.
  
  Solutions:
  
  Check Configuration: Review the SSO configuration in the SAP system. Ensure that the settings for the IdP are correct, including the issuer name and endpoint URLs.
