• What is the cause and solution for SAP error message SAML2082 - Authentication failed: No authorization to call ?

  The SAP error message SAML2082 indicates that there is an authentication failure due to a lack of authorization to call a specific service or resource. This error typically occurs in the context of Single Sign-On (SSO) scenarios using SAML (Security Assertion Markup Language).
  Causes:
  
  Missing Authorizations: The user does not have the necessary authorizations to access the requested resource or service.
  Incorrect SAML Configuration: The SAML configuration might be incorrect, leading to authentication issues.

  Solutions:
  
  
  Check User Authorizations:
  
  Verify that the user has the necessary roles and authorizations to access the resource. This can be done using transaction codes like SU01 (User Maintenance) and PFCG (Role Maintenance).
  Ensure that the user is assigned to the correct roles that include the necessary authorizations.
  
  
  
  Review SAML Configuration:
  
  Check the SAML configuration settings in both the SAP system and the Identity Provider. Ensure that the SAML assertions are correctly configured and that the user attributes are being passed correctly.
  Validate the SAML certificates and ensure they are up to date.
  
  
  
  Check Identity Provider Settings:
  
  Ensure that the Identity Provider is correctly configured to authenticate users and that it is properly integrated with the SAP system.
  Review the logs on the IdP side to identify any issues during the authentication process.
  
  
  
  Service Provider Configuration:

  Consult Logs:
  
  Check the SAP system logs (transaction SLG1) for more detailed error messages that can provide additional context about the failure.
  Review the SAML trace logs if available, to see the details of the SAML request and response.
  
  
  
  Testing:
