• What is the cause and solution for SAP error message DDLS367 - Parent & has aggregate function or group by; extension not possible ?

  The SAP error message DDLS367 indicates that there is an issue with the SQL statement being executed, specifically related to the use of aggregate functions or the GROUP BY clause in a database view or table definition. This error typically arises when you attempt to extend a database object (like a view) that includes aggregate functions or a GROUP BY clause, which is not allowed in certain contexts.
  Cause:
  
  Aggregate Functions: The SQL statement includes aggregate functions (e.g., SUM, COUNT, AVG, etc.) that summarize data.
  GROUP BY Clause: The SQL statement uses a GROUP BY clause to group records based on one or more columns.
  Extension Attempt: You are trying to extend a database object that is defined with these constructs, which is not permitted.
  
  Solution:
  To resolve the DDLS367 error, consider the following approaches:
  
  
  Review the SQL Statement: Check the SQL statement for any aggregate functions or GROUP BY clauses. If you are trying to extend a view or table that contains these, you will need to modify your approach.
  
  
  Create a New View: Instead of extending the existing view, create a new view that incorporates the necessary logic without using aggregate functions or GROUP BY. This new view can then be used in your application.
  
  
  Use a Different Approach: If you need to perform aggregations, consider using a different method, such as creating a report or using a different type of query that does not require extending the existing object.
  
  
  Check for Dependencies: Ensure that there are no dependencies on the object you are trying to extend. If other objects depend on it, you may need to address those dependencies first.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific guidelines on how to handle views and tables with aggregate functions.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or solutions for this error.
