About History Old data never dies, it just becomes history. For all of you who worry about destroying data when you make an adjustment in PPS, the History DataBase is where the old data goes.
History screens work like other inquiry screens.
Pages run from most current to least current. Instead you'll see distributions listed in straight chronological order top to bottom from most current to least current. Call this the distribution's ghost. It's what the old distribution used to look like before it was changed with newer data. Look up from this line and you'll see that at some point the distribution was ended.
