• What is the cause and solution for SAP error message SAML2_CONFIG_UI010 - All suitable trusted entities have already been added ?

  The SAP error message SAML2_CONFIG_UI010 indicates that when configuring SAML (Security Assertion Markup Language) in the SAP system, all suitable trusted entities (identity providers or service providers) have already been added to the configuration. This typically occurs when you attempt to add a new trusted entity that is either already present in the configuration or does not meet the criteria for being added.
  Cause:
  
  Duplicate Entry: The most common cause is that the entity you are trying to add is already listed in the trusted entities.
  Configuration Limitations: There may be restrictions on the number of entities that can be added, or the entity you are trying to add does not meet the necessary criteria.
  Incorrect Configuration: The configuration settings for the SAML setup may not be correctly defined, leading to issues when trying to add new entities.
  
  Solution:
  
  
  Check Existing Trusted Entities:
  
  Go to the SAML configuration in your SAP system (transaction code SAML2).
  Review the list of existing trusted entities to see if the entity you are trying to add is already present.
  
  
  
  Remove or Modify Existing Entries:
  
  If the entity is already present and you need to make changes, consider modifying the existing entry instead of adding a new one.
  If there are duplicates, remove the unnecessary entries.
  
  
  
  Verify Configuration Settings:
  
  Ensure that the configuration settings for SAML are correctly defined. This includes checking the metadata, certificates, and other related settings.
  Make sure that the entity you are trying to add is correctly configured as a trusted entity.
  
  
  
  Consult Documentation:
