This error indicates that there are duplicate item numbers in the ASN data being processed, which violates the requirement for item numbers to be unique.
  Cause:
  
  Duplicate Item Numbers: The most common cause of this error is that the ASN being processed contains multiple entries for the same item number. This can happen due to data entry errors, incorrect data extraction from source systems, or issues in the integration process.

  Solution:
  
  Check ASN Data: Review the ASN data being processed to identify any duplicate item numbers. This can often be done by exporting the ASN data to a spreadsheet and using functions to find duplicates.
  Correct Duplicates: Once duplicates are identified, correct the ASN data by ensuring that each item number is unique. This may involve removing duplicate entries or consolidating them if necessary.
  Data Validation: Implement data validation checks in the system or during the data import process to prevent duplicates from being created in the first place.
  Review Integration Processes: If the ASN data is coming from an external system, review the integration processes to ensure that they are correctly handling item numbers and not creating duplicates.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling ASNs and ensuring data integrity.

  User Exits and BAdIs: If you have custom logic in your ASN processing, review any user exits or Business Add-Ins (BAdIs) that may be affecting how item numbers are handled.
  Testing: After making corrections, test the ASN processing with a small set of data to ensure that the issue is resolved before processing larger batches.
  
  By following these steps, you should be able to resolve the error and ensure that your ASN processing runs smoothly.
