• What is the cause and solution for SAP error message SMT_CONFIG120 - Structure &1 is already specified as a preceeding structure ?

  The SAP error message SMT_CONFIG120 indicates that there is a configuration issue related to the structure definition in the SAP system. Specifically, it means that the structure you are trying to define or configure has already been specified as a preceding structure in the context of a certain configuration or mapping process.
  Cause:
  
  Duplicate Structure Definition: The structure you are trying to add or configure is already defined as a preceding structure in the same context. This can happen if you are trying to create a mapping or configuration that involves multiple structures and you inadvertently include the same structure more than once.
  Incorrect Configuration: There may be a logical error in the way the structures are set up, leading to conflicts in the configuration.
  
  Solution:
  
  Review Configuration: Check the configuration settings where the error occurred. Look for the structure that is causing the conflict and see if it has been defined multiple times.
  Remove Duplicate Entries: If you find that the structure is indeed listed more than once, remove the duplicate entry to resolve the conflict.
  Check Preceding Structures: Ensure that the preceding structures are correctly defined and that there are no logical errors in the way they are set up.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure structures and mappings in your specific context.
  Testing: After making changes, test the configuration to ensure that the error is resolved and that the system behaves as expected.
