• What is the cause and solution for SAP error message AD103 - The name & does not start with a letter ?

  The SAP error message AD103 indicates that a name (such as a variable, function, or object name) does not start with a letter. This is a common issue in SAP ABAP programming and can occur in various contexts, such as when defining variables, function modules, or other identifiers.
  Cause:
  The error occurs because SAP has specific naming conventions that must be followed. According to these conventions:
  
  Identifiers (like variable names, function names, etc.) must start with a letter (A-Z or a-z).
  Identifiers can contain letters, numbers (0-9), and underscores (_), but they cannot start with a number or special character.
  
  Solution:
  To resolve the error, you should:
  
  Check the Identifier: Review the name that is causing the error. Ensure that it starts with a letter.
  Rename the Identifier: If the name starts with a number or special character, rename it to start with a letter. For example:
  
  Change 1variable to var1 or myVariable.
  Change @myVar to myVar.
  
  
  Follow Naming Conventions: Ensure that the rest of the identifier follows SAP's naming conventions. Avoid using reserved keywords and ensure that the name is meaningful and descriptive.
