• What is the cause and solution for SAP error message DA103 - Control structure not concluded with & ?

  The SAP error message DA103, which states "Control structure not concluded with &," typically occurs in the context of ABAP programming. This error indicates that there is an issue with the control structure in your code, specifically that a control structure (like a loop or conditional statement) is not properly concluded.
  Cause:
  The error is usually caused by one of the following:
  
  Incomplete Control Structure: You have started a control structure (like IF, CASE, LOOP, etc.) but have not properly closed it with the corresponding ENDIF, ENDCASE, or ENDLOOP.
  Incorrect Syntax: There may be a syntax error in the control structure that prevents it from being recognized as complete.
  Missing or Extra Characters: Sometimes, missing or extra characters (like a missing & in a string concatenation) can lead to this error.
  
  Solution:
  To resolve the DA103 error, follow these steps:
  
  
  Check Control Structures: Review your code for any control structures that are not properly closed. Ensure that every IF has a corresponding ENDIF, every LOOP has an ENDLOOP, and every CASE has an ENDCASE.
  Example:
  IF condition.
      " some code
  ENDIF.  " Ensure this is present
  
  
  Review Syntax: Make sure that the syntax of your control structures is correct. Look for any misplaced or missing keywords.
  
  
  Look for Concatenation Issues: If you are using string concatenation, ensure that you are using the & operator correctly. For example:
  DATA(result) = 'Hello' && ' World'.  " Correct usage
  
  
  Use Syntax Check: Use the syntax check feature in the ABAP editor (transaction SE38 or SE80) to identify any syntax errors in your code.
  
  
  Debugging: If the error persists, consider debugging the program to see where the control structure is being incorrectly interpreted.
