How to expose the target pin for "set" variables

Hello all, I’m just starting to get into blueprints (total newbie) and I’m seeing that on certain variables when someone has it to “set” sometimes they have a object pins showing that can receive input. How do I expose this for my variables? Is it a simple check box or is it something that has been taken out since newer versions of the engine exist?

This is what I’m referring to.

You get the target pin when you call a variable from another BP or a component. Otherwise the variable is already in the owner BP so it doesnt need a target reference.

“another BP or a component” = external class ;]

im setting it from a destroy component and is not allowing me to get the set variable with the target pin. please help
