  The SAP error message FUNC_ADT020, which states "The statement FUNCTION is missing," typically occurs in the context of ABAP programming when the system expects a FUNCTION statement but does not find one. This can happen in various scenarios, such as when defining a function module or when using function calls in your code.
  Causes:
  
  Missing FUNCTION Statement: The most straightforward cause is that the FUNCTION statement is simply missing from your code.
  Syntax Errors: There may be syntax errors in the code that prevent the parser from recognizing the FUNCTION statement.
  Incorrect Structure: The structure of the function module or method may not be correctly defined, leading to the absence of the expected FUNCTION statement.
  Code Incomplete: The code might be incomplete or improperly copied, leading to missing parts.
  
  Solutions:

  Check for Incomplete Code: If you copied code from another source, ensure that the entire function definition was copied. Look for any missing parts that could lead to this error.
  
  
  Use the ABAP Debugger: If the error occurs during runtime, use the ABAP debugger to step through the code and identify where the function call is failing.
