I have four tabs in a Excel 2010 database that have similar pivot tables that point to the same data table. I added Calculated Items to each pivot table. In one of the pivot tables I wanted to remove the calculated items. The strangest thing happens when I do so....that calculated fields in all of the other pivot tables go away and if I put them back they return to each of them. It seems like the tables must be joined somehow....no clue. How do I stop these pivot tables from sharing the same attributes?
