  Examine Mapping Logic: Review the mapping logic to ensure that it correctly identifies change indicators. Make adjustments as necessary to ensure that the logic can uniquely determine changes.
  
  
  Test with Sample Data: If possible, test the mapping process with a smaller set of sample data to identify where the issue may be occurring. This can help isolate the problem.
  
  
  Consult Documentation: Refer to SAP documentation or help resources related to data collection and mapping for specific guidelines and best practices.
