This can happen due to various reasons, such as incorrect data handling, issues in the application logic, or problems with the data model.

  Duplicate Entries: The most common cause is that the application is trying to process multiple entries with the same node ID in a single update or delete operation.
  Incorrect Logic: There may be a flaw in the logic of the application that leads to the same node being processed multiple times.

  Solutions:
  
  Check for Duplicates: Review the data being processed to ensure that there are no duplicate node IDs. This can be done by checking the input data or the state of the business object before the operation.

  Implement Locking Mechanisms: If concurrency is an issue, consider implementing locking mechanisms to prevent multiple transactions from affecting the same node simultaneously.
  Debugging: Use debugging tools to trace the execution of the code and identify where the duplicate node IDs are being introduced.
  Consult Documentation: Review the SAP documentation for BOPF and the specific business object you are working with to ensure that you are following best practices.
