If I pull the wrong folder, put a piece of paper in it, then immediately realize it's the wrong folder - all I have to do is pull the paper out and put it in the right folder. I don't leave it there with a sticky note stating it's a mistake.
In my opinion, electronic records should work the same way. If you save something to the wrong chart and realize it immediately, you should be able to delete it. The time frame to allow that should be small - maybe just a minute or two. Anything beyond that time frame would stay in the chart and require an addendum.
