This error indicates that there are duplicate data elements within a structure, which can lead to ambiguity in data handling.
  Cause:

  Solution:
  
  Check Structure Definition: Review the structure definition in the ABAP Dictionary (transaction SE11). Look for duplicate entries of data elements and remove or rename them to ensure that each data element is unique.
  Use Unique Names: Ensure that all data elements within the structure have unique names. If necessary, rename the conflicting elements to avoid duplication.
  Rebuild the Structure: If the structure is complex, consider rebuilding it from scratch, ensuring that each data element is distinct.
  Check for Inherited Structures: If the structure inherits from another structure, ensure that the parent structure does not have conflicting data elements.
  Transport Requests: If this error occurs after a transport request, check if the transport included changes to the data structure that might have introduced duplicates.
