LetRbe a ring andXa chain complex ofR-modules. It is proven that if each termis Ding injective inR-Mod for all, and there exists an integerksuch that eachis Ding injective inR-Mod for all, thenXis Ding injective in. IfRis a left coherent ring, then a chain complexXis Ding injective if and only if each termis Ding injective inR-Mod for all.
