• What is the cause and solution for SAP error message KW351 - Missing single quotation mark (') ?

  The SAP error message KW351, which indicates a "Missing single quotation mark (')", typically occurs in the context of ABAP programming or when dealing with string literals in SAP. This error suggests that there is an issue with the syntax of your code, specifically related to string delimiters.
  Cause:
  
  Unmatched Quotes: The most common cause is that a string literal is not properly enclosed in single quotation marks. For example, if you start a string with a single quote but forget to close it, SAP will throw this error.
  Concatenation Issues: If you are concatenating strings and one of the parts is missing a closing quote, it can lead to this error.
  Dynamic SQL Statements: If you are constructing dynamic SQL statements and forget to properly quote string values, this error can occur.
  Copy-Paste Errors: Sometimes, copying and pasting code from other sources can introduce formatting issues, such as mismatched quotes.
  
  Solution:
  
  
  Check Your Code: Review the line of code indicated in the error message. Ensure that all string literals are properly enclosed in single quotes.
  
  Example: Instead of DATA(my_string) = 'Hello World; (missing closing quote), it should be DATA(my_string) = 'Hello World';.
  
  
  
  Verify Concatenation: If you are concatenating strings, ensure that each part is correctly quoted.
  
  Example: DATA(my_string) = 'Hello ' + 'World'; is correct, while DATA(my_string) = 'Hello ' + 'World; (missing closing quote) will cause the error.
  
  
  
  Dynamic SQL: If you are using dynamic SQL, ensure that all string values are properly quoted.
  
  Example: CONCATENATE 'SELECT * FROM table WHERE field = ' value INTO sql_query. should ensure that value is properly quoted.
  
  
  
  Use Syntax Check: Use the syntax check feature in the ABAP editor (Ctrl + F2) to identify and correct syntax errors.
  
  
  Debugging: If the error is not immediately apparent, consider using debugging tools to step through the code and identify where the issue arises.
