GF003 - Details

• The SAP error message GF003, which states "Global object already exists (possibly in other components)," typically occurs when there is an attempt to create or activate a global object (such as a function module, class, or data element) that already exists in the SAP system. This can happen due to naming conflicts or when multiple components are trying to define the same global object.
  Causes:
  
  Naming Conflicts: The most common cause is that the object you are trying to create has the same name as an existing object in the system.
  Transport Issues: If you are working in a development environment and have transported objects from another system, there may be conflicts with existing objects.
  Multiple Components: The object may exist in different components or packages, leading to conflicts when trying to activate or create a new one.
  Namespace Issues: If you are using a custom namespace, ensure that the object name does not conflict
