• What is the cause and solution for SAP error message SDDL_PARSER_MSG125 - The GROUP BY list in view & cannot be extended ?

  The SAP error message SDDL_PARSER_MSG125 indicates that there is an issue with the SQL query related to a view in SAP, specifically that the GROUP BY clause cannot be extended. This typically occurs when the SQL query is trying to group by fields that are not part of the select list or when there are inconsistencies in the fields being aggregated.
  Cause:
  
  Inconsistent Fields: The fields in the GROUP BY clause must match the fields in the SELECT statement. If there are fields in the SELECT that are not included in the GROUP BY, it can lead to this error.
  Aggregation Issues: If you are using aggregate functions (like SUM, COUNT, AVG) in your SELECT statement, all non-aggregated fields must be included in the GROUP BY clause.
  View Definition: The view definition may have been altered or incorrectly defined, leading to a mismatch between the GROUP BY and the selected fields.
  
  Solution:
  
  Check the SQL Query: Review the SQL query that is causing the error. Ensure that all non-aggregated fields in the SELECT statement are included in the GROUP BY clause.
  Modify the View: If the view definition is incorrect, you may need to modify it to ensure that the GROUP BY clause is correctly defined.
  Use Aggregate Functions: If you are trying to select fields that are not aggregated, consider using aggregate functions for those fields or including them in the GROUP BY clause.
  Testing: After making changes, test the query again to ensure that the error is resolved.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP documentation for SQL syntax and guidelines on using GROUP BY clauses.
