Error Pipeline - Parent Child

I was wondering about a best practice on error pipelines.

I’ve got one that captures an error, I format it and send an email. All that’s good.

I was wonder…when we have a parent child set of pipelines…does the error pipeline need to be set at ALL pipelines in the parent child…or should I only put it at the parent level? I’ve put it at all levels for a while now, but not sure if that’s even needed. I haven’t found much on this and figured I’d throw it out to the group here.



@snaplogic any tips here?
