Depending on the scope and requirements of your implementation, you can create new components or copy, modify, or extend the predefined components.
Duplicating an integration component and modifying the copy has several advantages. The copy of an integration component becomes a user-defined entity, and modification restrictions that apply to the predefined component do not apply to the copy. The original version of the component is unchanged. To avoid modifying a component while it is being used for transaction processing, perform all modifications in administrator mode.
