This error indicates that there are duplicate field names within the model you are trying to create or modify.
  Cause:
  
  Duplicate Field Names: The most common cause of this error is that you have defined multiple fields with the same name within the same model or InfoProvider. SAP requires that each field name be unique to avoid confusion and ensure data integrity.
  Field Name Conflicts: If you are merging or combining different data sources, there may be conflicts in field names that need to be resolved.

  Solution:
  
  Check Field Names: Review the fields defined in your model. Ensure that each field has a unique name. If you find duplicates, rename them to ensure uniqueness.
  Review Data Sources: If you are combining multiple data sources, check the field names in each source. You may need to rename fields in one or more sources to avoid conflicts.
  Use Aliases: If you need to keep similar field names for clarity, consider using aliases or prefixes to differentiate them.
  Recreate the Model: If the issue persists and you cannot identify the duplicates, consider recreating the model from scratch, ensuring that you define unique field names from the beginning.
  Check for Hidden Fields: Sometimes, fields may not be immediately visible in the model configuration. Ensure that you check for any hidden or system-generated fields that may be causing the conflict.
