  The SAP error message FDT_CORE303 indicates that there is a problem with the XML document being processed, specifically that an object with a given ID occurs multiple times. This can happen in scenarios where the XML structure is expected to have unique identifiers for certain elements, but duplicates are found.
  Cause:
  
  Duplicate IDs: The most common cause of this error is that the XML document contains multiple instances of an object with the same ID. This violates the uniqueness constraint expected by the system.
  Incorrect Mapping: If the XML is being generated or transformed from another format, there may be issues in the mapping logic that lead to duplicates.

  Solution:
  
  Check the XML Document: Review the XML document to identify where the duplicate IDs are occurring. You can use XML validation tools or parsers to help with this.
  Modify the Source Data: If the duplicates are due to issues in the source data, correct the data to ensure that each object has a unique ID.
  Adjust Mapping Logic: If the XML is generated from another format, review and adjust the mapping logic to ensure that it correctly handles uniqueness.
  Use Unique Identifiers: If possible, modify the logic to generate unique identifiers for objects that may otherwise have the same ID.
  Error Handling: Implement error handling in your XML processing logic to catch and manage duplicates gracefully.
  
  Related Information:
  
  XML Schema Definition (XSD): If you are using an XSD to validate your XML, ensure that the schema correctly defines the uniqueness constraints for the elements.
