Overwriting Data
You can overwrite data that's currently in CFO Scoreboard by uploading new data to replace it.
If you upload a set of Excel files that contain months you have already previously uploaded, CFO Scoreboard will replace the existing figures in those old months entirely with the new figures that you are providing. Whether they have changed in the new Excel files or not, CFO Scoreboard will use the new data to overwrite the old completely.
Note that this logic does not have anything to do with accidentally overwriting or deleting date ranges that you aren't touching. So for instance if you have already uploaded 2012 - 2014, and you upload a new Excel batch with revised numbers for 2014, then CFO Scoreboard will only overwrite the figures for 2014, and will not touch 2012 or 2013.
