I am getting ready to file a continuing activity SAR, when I notice on my original SAR I made an error with the dates in the narrative. So I know I need to amend the original SAR, ok. My question is, when I go to file the continuing activity SAR do I reference the DCN from the original SAR or the amended SAR?

I would reference the Amended SAR as that is the one with the correct data, but still mention the original one and its filing date, so anyone following up on it gets the whole picture.
