• What is the cause and solution for SAP error message ACI_COMPILER_GENERIC131 - runaway macro definition, missed 'END-OF-DEFINITION.' ?

  The SAP error message ACI_COMPILER_GENERIC131 indicates that there is a runaway macro definition in your ABAP code. This typically occurs when a macro is defined but not properly terminated with an END-OF-DEFINITION statement. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Runaway Macro Definition: This error usually arises when a macro is defined but the END-OF-DEFINITION statement is missing. The ABAP compiler expects this statement to signify the end of the macro definition.
  Syntax Errors: There may be syntax errors in the macro definition that prevent the compiler from recognizing the end of the definition.
  Nested Macros: If you have nested macros, ensure that each macro is properly defined and terminated.
  
  Solution:
  
  Check Macro Definition: Review the macro definition in your code. Ensure that every macro defined with DEFINE has a corresponding END-OF-DEFINITION.
  DEFINE my_macro.
    " Macro content here
  END-OF-DEFINITION.
  
  Syntax Review: Look for any syntax errors within the macro. Ensure that all statements are correctly formatted and that there are no missing or extra characters.
  Comment Out Sections: If you are unable to find the issue, try commenting out sections of the macro to isolate the problem. This can help you identify where the definition is going wrong.
  Check for Nested Macros: If you are using nested macros, ensure that each one is properly defined and terminated. Each macro should have its own END-OF-DEFINITION.
  Use the ABAP Editor: Utilize the ABAP editor's syntax check feature (Ctrl + F2) to identify any syntax errors in your code.
  
  Related Information:
  
  Macro Definition Syntax: Familiarize yourself with the syntax for defining macros in ABAP. The basic structure is:
  DEFINE macro_name.
    " Macro content
  END-OF-DEFINITION.
  
  Documentation: Refer to the official SAP documentation for more details on macro definitions and best practices.
  Debugging Tools: Use debugging tools available in the ABAP Workbench to step through your code and identify where the error occurs.
  
  By following these steps, you should be able to resolve the ACI_COMPILER_GENERIC131 error and ensure that your macro definitions are correctly structured.
