This typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are trying to create or maintain product master data, and the system detects a duplicate entry.
  Cause:

  Searching for the product using the product number or description.
  
  
  
  Modify Existing Product: If the product already exists and you need to make changes, modify the existing product instead of creating a new one.
  
  
  Data Cleanup: If you are migrating data, ensure that your data does not contain duplicates. Clean up the data before performing the upload.
  
  
  Consult Documentation: Review the SAP documentation or help files related to product master data management in APO for any specific guidelines or restrictions.
