• What is the cause and solution for SAP error message DDLS172 - No table or view is specified for column & after CASE ?

  The SAP error message DDLS172 ("No table or view is specified for column & after CASE") typically occurs in the context of SQL statements, particularly when using the CASE statement in a SQL query or view definition. This error indicates that the SQL parser cannot determine the source table or view for a column that is being referenced after a CASE statement.
  Cause:
  The error is usually caused by one of the following issues:
  
  
  Missing Table/View Reference: The column referenced in the CASE statement does not have an associated table or view specified. This can happen if the column is ambiguous or if the SQL statement does not clearly indicate which table the column belongs to.
  
  
  Incorrect Syntax: There may be a syntax error in the SQL statement that prevents the parser from correctly interpreting the CASE statement.
  
  
  Alias Issues: If you are using aliases in your SQL statement, the alias may not be properly defined or may not be recognized in the context of the CASE statement.
  
  
  Solution:
  To resolve the DDLS172 error, you can take the following steps:
  
  
  Specify the Table/View: Ensure that you explicitly specify the table or view from which the column is being selected. For example, instead of just using the column name, use the format table_name.column_name.
  SELECT 
      CASE 
          WHEN table_name.column_name = 'value' THEN 'result'
          ELSE 'other_result'
      END AS result_column
  FROM table_name
  
  
  Check Syntax: Review the SQL syntax to ensure that it is correct. Make sure that all parentheses are properly closed and that the CASE statement is correctly structured.
  
  
  Use Aliases Properly: If you are using aliases, ensure that they are defined correctly and are used consistently throughout the SQL statement.
  SELECT 
      CASE 
          WHEN t.column_name = 'value' THEN 'result'
          ELSE 'other_result'
      END AS result_column
  FROM table_name AS t
  
  
  Review Context: If the CASE statement is part of a larger query (e.g., a subquery or a join), ensure that the context is clear and that all necessary tables/views are included in the query.
  
  
  Related Information:
  
  SQL CASE Statement: The CASE statement is used to create conditional logic in SQL queries. It allows you to return different values based on certain conditions.
  Debugging SQL Queries: When encountering SQL errors, it can be helpful to break down the query into smaller parts to isolate the issue. Testing individual components can help identify where the problem lies.
  SAP Documentation: For more detailed information on SQL syntax and error messages, refer to the official SAP documentation or the ABAP programming guidelines.
  
  By following these steps, you should be able to resolve the DDLS172 error and successfully execute your SQL query.
