• What is the cause and solution for SAP error message SIC_NORM_ENGINE020 - Position numbers not unique ?

  The SAP error message "SIC_NORM_ENGINE020 Position numbers not unique" typically occurs in the context of the SAP normalization engine, which is used for various data processing tasks, including data cleansing and standardization. This error indicates that there are duplicate position numbers in the data being processed, which prevents the normalization engine from functioning correctly.
  Cause:
  
  Duplicate Position Numbers: The most common cause of this error is that the data being processed contains multiple entries with the same position number. This can happen due to data entry errors, data imports, or issues with data extraction processes.
  Data Structure Issues: If the data structure does not enforce uniqueness for position numbers, it can lead to duplicates being present in the dataset.
  Configuration Issues: Incorrect configuration of the normalization engine or related settings may also lead to this error.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Use SQL queries or SAP reporting tools to identify the records with duplicate position numbers in the relevant tables.
  For example, you can run a query to count occurrences of each position number and find those that appear more than once.
  
  
  
  Data Cleansing:
  
  Once duplicates are identified, you can either remove the duplicates or consolidate them based on your business rules.
  Ensure that the data is cleaned before reprocessing it through the normalization engine.
  
  
  
  Enforce Uniqueness:
  
  If applicable, modify the data model to enforce uniqueness on position numbers. This can be done by adding constraints in the database or adjusting the data entry processes to prevent duplicates.
  
  
  
  Review Configuration:
  
  Check the configuration settings of the normalization engine to ensure that it is set up correctly to handle the data being processed.
  
  
  
  Testing:
  
  After making the necessary changes, test the normalization process again to ensure that the error does not reoccur.
