  The SAP error message AXT_MODEL154, which states "Table or structure &1 already exists," typically occurs when you are trying to create a table or structure in the Data Dictionary (SE11) that already exists in the system. This can happen during various operations, such as creating a new table, modifying an existing one, or during transport requests.
  Cause:
  
  Duplicate Definition: You are attempting to create a table or structure with a name that is already in use in the SAP system.
  Transport Issues: If you are importing a transport request that contains a table or structure definition that already exists in the target system.
  Development Environment: If multiple developers are working on the same object and one of them has already created it.
  
  Solution:
  
  
  Check Existing Objects: 
  
  Use transaction SE11 (Data Dictionary) to check if the table or structure with the specified name already exists. If it does, you may need to modify the existing object instead of creating a new one.

  Delete or Modify: 
  
  If the existing table or structure is no longer needed, you can delete it (if you have the necessary authorizations) or modify it as required.
  
  
  
  Check for Active Versions: 
  
  Ensure that there are no active versions of the object that might be causing the conflict. You can check this in SE11 or SE80.
