• What is the cause and solution for SAP error message SDDL_PARSER_MSG022 - obsolete: $$EXTENSION and GROUP BY are not valid together ?

  The SAP error message SDDL_PARSER_MSG022 indicates that there is an issue with the use of the $$EXTENSION keyword in conjunction with a GROUP BY clause in a query. This error typically arises in the context of SAP's Semantic Data Definition Language (SDDL) or when working with certain data models in SAP systems.
  
  Cause:
  The error occurs because the $$EXTENSION keyword is not compatible with the GROUP BY clause. In SQL and similar query languages, GROUP BY is used to aggregate data based on specified columns, while $$EXTENSION is often used to extend or modify the behavior of a query. When these two are used together, the system cannot process the request correctly, leading to the error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Query: Check the SQL or SDDL query that is causing the error. Look for the use of $$EXTENSION and GROUP BY in the same statement.
