  Cause:
  The error occurs due to the following reasons:
  
  Incorrect Configuration: You may be trying to configure a TBO to link more than two models, which is not supported.
  Model Definition Issues: The models you are trying to link may not be defined correctly or may not adhere to the expected structure.
  Misunderstanding of TBO Functionality: There may be a misunderstanding regarding how TBOs are intended to function within the SAP system.
  
  Solution:
  To resolve the error, consider the following steps:
  
  
  Review TBO Configuration:
  
  Ensure that the TBO is configured to link only two models. Check the settings in the TBO configuration to confirm that you are not attempting to link more than two models.
  
  
  
  Check Model Definitions:
  
  Verify that the models you are trying to link are correctly defined and that they meet the requirements for linking. Ensure that both models are compatible with the TBO.
  
  
  
  Consult Documentation:

  Simplify the Link:
  
  If you need to link more than two models, consider creating multiple TBOs, each linking only two models at a time, rather than trying to link all models with a single TBO.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the configuration to ensure that the error no longer occurs.
  
  
  
  Seek Support:
