This typically occurs in the context of data structures, such as when working with Business Object (BO) definitions, data models, or when importing/exporting data.
  Cause:
  
  Duplicate Attribute Names: The most common cause of this error is that the same attribute name has been defined more than once within the same node of a data structure or object definition.
  Incorrect Data Model: If you are working with a data model that has been manually edited or generated, it may contain errors leading to duplicate definitions.
  Import/Export Issues: If you are importing or exporting data structures, the source data may have duplicates that are not allowed in the target structure.
  
  Solution:
  
  Check the Data Structure: Review the definition of the node mentioned in the error message. Look for any duplicate attribute names and ensure that each attribute is unique within that node.
  Modify the Definition: If duplicates are found, modify the data structure to ensure that each attribute name is unique. This may involve renaming attributes or removing unnecessary duplicates.
  Validate the Model: After making changes, validate the data model or object definition to ensure that it complies with the required structure and does not contain any further errors.
  Re-import/Export: If the error occurred during an import or export process, ensure that the source data is corrected before attempting the operation again.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidelines on defining data structures and objects. This can provide insights into best practices for naming conventions and structure.
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to inspect and modify data structures.
  Debugging: If the error persists, consider using debugging tools within SAP to trace the source of the error and identify where the duplicate attribute names are being generated.
  
  By addressing the root cause of the duplicate attribute names and ensuring that your data structures are correctly defined, you should be able to resolve the STOBJ120 error.
