• What is the cause and solution for SAP error message DDLS141 - Only identifiers are currently allowed in the "group by" clause ?

  The SAP error message DDLS141 indicates that there is an issue with the SQL query you are trying to execute, specifically in the GROUP BY clause. This error occurs when the GROUP BY clause contains expressions or calculations instead of just identifiers (column names).
  Cause:
  The primary cause of this error is that the GROUP BY clause is expected to contain only column names (identifiers) and not any expressions, functions, or calculations. For example, if you have a query like this:
  SELECT column1, SUM(column2)
  FROM table_name
  GROUP BY column1 + column3
  This will trigger the DDLS141 error because column1 + column3 is an expression, not a simple identifier.
  Solution:
  To resolve this error, you need to modify your SQL query so that the GROUP BY clause only includes column names. Here’s how you can adjust the previous example:
  
  Identify the columns you want to group by: Ensure that you are only using column names in the GROUP BY clause.
  Use the correct identifiers: Rewrite the query to use only identifiers in the GROUP BY clause.
  
  For example, you can rewrite the query as follows:
  SELECT column1, SUM(column2)
  FROM table_name
  GROUP BY column1
  Related Information:
  
  SQL Syntax: The SQL standard requires that the GROUP BY clause only contains column names. This is to ensure that the grouping is done based on distinct values of those columns.
  Aggregate Functions: When using aggregate functions like SUM(), COUNT(), etc., ensure that any non-aggregated columns in the SELECT statement are included in the GROUP BY clause.
  Debugging Queries: If you encounter this error, review your SQL query carefully, focusing on the GROUP BY clause and ensuring it adheres to the expected syntax.
  
  By following these guidelines, you should be able to resolve the DDLS141 error and successfully execute your SQL query.
