• What is the cause and solution for SAP error message SAML2_CONFIG_UI004 - All supported operation modes already exist ?

  The SAP error message SAML2_CONFIG_UI004: All supported operation modes already exist typically occurs in the context of configuring SAML (Security Assertion Markup Language) for Single Sign-On (SSO) in SAP systems. This error indicates that the system is trying to create or modify an operation mode that already exists in the SAML configuration.
  Cause:
  The error is caused by attempting to add a new operation mode in the SAML configuration when the operation mode you are trying to add is already defined. In SAML configurations, operation modes define how the SSO will function, and each mode must be unique.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Operation Modes:
  
  Go to the SAML2 configuration in your SAP system (transaction code SAML2).
  Review the existing operation modes listed in the configuration. Identify if the operation mode you are trying to add already exists.
  
  
  
  Modify Existing Configuration:
  
  If the operation mode already exists, you can either modify the existing configuration or delete it if it is no longer needed.
  To modify, select the existing operation mode and make the necessary changes.
  
  
  
  Delete Duplicate Operation Mode:
  
  If you find that the operation mode is a duplicate and not needed, you can delete it from the configuration.
  
  
  
  Add New Operation Mode:
  
  If you need to add a new operation mode, ensure that it has a unique name that does not conflict with existing modes.
  
  
  
  Save Changes:
  
  After making the necessary changes, save the configuration and check if the error persists.
