I have an excel workbook with multiple pivot tables all using the data sheet. When I group or ungroup items in one pivot table it changes all the others as well. How do I stop this? I just want each pivot table to be independent of each other while using the same data sheet. I tried recreating the pivot tables without copying an existing one but it just keeps happening. I have never seen this before. I cant find answers to this one when I search. Thank you.
