  The SAP error message SDEST052: Cannot send SSO ticket typically occurs in scenarios where Single Sign-On (SSO) is configured but there is an issue with the generation or transmission of the SSO ticket. This can happen in various contexts, such as when trying to access SAP systems or when integrating with other applications.

  Authorization Issues: The user may not have the necessary authorizations to generate or send the SSO ticket.
  System Time Mismatch: If the system time on the SAP server and the IdP are not synchronized, it can lead to issues with ticket validation.
