I have a procedure that calls several other procedures.

I have changed one of the embedded procedures and can run that independently and get the results I expect, I was able to compile it and it works.]

My question is do I need to compile the parent procedure again, or should it just pick up the new version of the prod.

And if I am calling this with an app that is connected, do I need to stop that app and restart it, or will that use the new version?
