  Check Existing Function Modules: Use transaction code SE37 (Function Module) to search for existing function modules. You can check if the name you want to use is already taken.
  Namespace Considerations: If you are working in a specific namespace, ensure that the name you are trying to use is not reserved or already assigned within that namespace.
