• What is the cause and solution for SAP error message MZ089 - The name of an exception cannot begin with ~ ?

  The SAP error message MZ089, which states "The name of an exception cannot begin with ~," typically occurs in the context of ABAP programming when defining exceptions in a method or function module. This error indicates that the name of an exception you are trying to define or use starts with the tilde character (~), which is not allowed in ABAP.
  Cause:
  
  Invalid Exception Name: The exception name you are trying to define or reference starts with the tilde character (~). In ABAP, exception names must follow specific naming conventions and cannot start with certain special characters.
  Typographical Error: It could also be a typographical error where the tilde was mistakenly included in the exception name.
  
  Solution:
  
  Rename the Exception: Change the name of the exception to ensure it does not start with the tilde character. For example, if your exception is named ~my_exception, rename it to my_exception or exception_my.
  Check for Typos: Review your code to ensure that there are no unintended characters in the exception name. Correct any typos that may have led to the inclusion of the tilde.
  Follow Naming Conventions: Ensure that the exception names you are using adhere to ABAP naming conventions. Typically, exception names should be descriptive and start with a letter.
  
  Related Information:
  
  ABAP Naming Conventions: Familiarize yourself with the naming conventions in ABAP to avoid similar issues in the future. Exception names should be meaningful and follow the standard practices.
  Documentation: Refer to the official SAP documentation for more details on exception handling in ABAP, including how to define and use exceptions properly.
  Debugging: If you encounter this error during runtime, use the ABAP debugger to trace back to where the exception is being raised or handled to identify the problematic name.
