• What is the cause and solution for SAP error message SDDL_PARSER_MSG476 - GROUP BY cannot be used in projection views ?

  The SAP error message SDDL_PARSER_MSG476 indicates that there is an issue with the use of the GROUP BY clause in projection views. This error typically arises when you attempt to create or execute a projection view that includes a GROUP BY clause, which is not allowed in this context.
  Cause:
  The primary cause of this error is the misuse of the GROUP BY clause in a projection view definition. In SAP, projection views are designed to select specific fields from a data source without aggregating data. The GROUP BY clause is used for aggregating data, which contradicts the purpose of a projection view.
  Solution:
  To resolve this error, you should:
  
  
  Remove the GROUP BY Clause: If you are trying to create a projection view, ensure that you do not include any GROUP BY clauses in your SQL statement or view definition. Projection views should only include fields that you want to project without any aggregation.
  
  
  Use a Different View Type: If your intention is to aggregate data, consider using a different type of view, such as a Calculation View or Analytical View, which allows for aggregation and the use of GROUP BY.
  
  
  Check the View Definition: Review the SQL or the definition of the projection view to ensure that it adheres to the rules for projection views. Make sure that you are only selecting fields without any aggregation functions or grouping.
  
  
  Related Information:
  
  
  Projection Views: These are used to select specific columns from a table or a set of tables without performing any aggregation. They are typically used for reporting purposes where detailed data is required.
  
  
  Calculation Views: These allow for more complex data modeling, including the use of aggregations, joins, and calculations. If you need to perform aggregations, consider using a calculation view instead.
  
  
  SAP Documentation: For more detailed information, refer to the official SAP documentation regarding the different types of views and their usage, as well as best practices for data modeling in SAP HANA.
  
  
  By following these guidelines, you should be able to resolve the error and create the desired view without encountering the SDDL_PARSER_MSG476 error.
