This typically arises in the context of SAP's Landscape Transformation (SLT) or data migration scenarios where the system is trying to replicate or transform data from one system to another.
  Cause:
  
  Duplicate Field Names: The error is primarily caused by having duplicate field names in the modification overview. This can happen if the same field is being modified or mapped multiple times in the transformation rules or if there are conflicting definitions in the data model.

  Data Model Changes: Changes in the underlying data model that are not reflected in the replication or transformation settings can also cause this error.
  
  Solution:
  
  Review Modification Overview: Check the modification overview for the specific field names that are causing the conflict. Identify where the duplicates are occurring.
  Remove Duplicates: If you find that the same field is being modified multiple times, you will need to remove or consolidate these modifications to ensure that each field is only defined once.

  Check Configuration Settings: Ensure that the configuration settings for the data replication or transformation process are correct and do not contain conflicting definitions.
