  Solution:
  
  Check Number Range Configuration: Verify the number range configuration in the source system (SAP ERP) to ensure that it is set up correctly and does not conflict with reserved ranges.
  Review Data Source Settings: Check the settings of the data source in the BW system. Ensure that the data source is correctly configured and that the extraction settings are appropriate for the data being extracted.
  Update or Reconfigure Extraction: If necessary, update or reconfigure the extraction process to avoid using reserved number ranges. This may involve changing the extraction method or adjusting the data source settings.
