• What is the cause and solution for SAP error message FUNC_ADT105 - Editing EXIT_* function modules is not supported with ADT ?

  The SAP error message FUNC_ADT105 indicates that you are trying to edit an EXIT function module using the ABAP Development Tools (ADT) in Eclipse, which is not supported. EXIT function modules are special types of function modules that are used for user exits in SAP, and they have specific restrictions when it comes to editing.
  Cause:
  The primary cause of this error is that the ABAP Development Tools (ADT) do not support editing of function modules that are designated as user exits (EXIT_*). These function modules are typically used to allow customers to add their own functionality to standard SAP processes without modifying the original code. SAP restricts editing these function modules to maintain the integrity of the standard system.
  Solution:
  To resolve this issue, you have a few options:
  
  
  Use the SAP GUI: Instead of using ADT in Eclipse, you can use the traditional SAP GUI to edit the EXIT function module. You can access it via transaction SE37 (Function Builder) or SE80 (Object Navigator).
  
  
  Create a Z-Function Module: If you need to implement custom logic, consider creating your own Z-function module that can be called from the EXIT function module. This way, you can maintain your custom code separately without directly modifying the EXIT function module.
  
  
  Check for Enhancements: If you are looking to add functionality, check if there are enhancement spots or BAdIs (Business Add-Ins) available for the specific functionality you are working with. These are often more flexible and supported for custom development.
  
  
  Review Documentation: Always refer to the official SAP documentation for guidelines on user exits and the best practices for extending standard functionality.
  
  
  Related Information:
  
  User Exits: User exits are predefined points in SAP programs where you can add your own code. They are typically implemented as function modules with names starting with EXIT_.
  Enhancement Framework: SAP provides an enhancement framework that allows for more flexible and maintainable customizations compared to user exits.
  ABAP Development Tools (ADT): ADT is an Eclipse-based development environment for ABAP programming, which provides modern development features but has certain limitations regarding legacy objects like EXIT function modules.
