• What is the cause and solution for SAP error message SDDL_PARSER_MSG023 - Obsolete: this expression and GROUPB BY are not valid together ?

  The SAP error message SDDL_PARSER_MSG023 indicates that there is an issue with the use of an expression in conjunction with the GROUP BY clause in a query. This error typically arises when the SQL syntax or the logic of the query is not correctly structured, particularly when using aggregate functions or expressions that are not compatible with grouping.
  Cause:
  
  Invalid Expression: The expression used in the SELECT statement is not compatible with the GROUP BY clause. This often happens when you try to select a non-aggregated column that is not included in the GROUP BY clause.
  Obsolete Syntax: The error message suggests that the expression being used is considered obsolete or deprecated in the context of the current SQL standards or the specific version of SAP you are using.
  Misconfiguration: There may be a misconfiguration in the way the query is constructed, leading to the use of unsupported expressions.
  
  Solution:
  
  
  Review the Query: Check the SQL query for any expressions that are not valid with GROUP BY. Ensure that all non-aggregated columns in the SELECT statement are included in the GROUP BY clause.
  Example:
  SELECT column1, SUM(column2)
  FROM table_name
  GROUP BY column1;  -- Ensure column1 is in GROUP BY
  
  
  Use Aggregate Functions: If you are trying to retrieve summary data, ensure that you are using aggregate functions (like SUM, COUNT, AVG, etc.) correctly and that any columns not aggregated are included in the GROUP BY clause.
  
  
  Check for Deprecated Features: If you are using any features or syntax that may be considered obsolete, refer to the SAP documentation for the version you are using to find the recommended practices.
  
  
  Test the Query: After making adjustments, test the query to ensure that it runs without errors.
