There is a complex query required that I find it can only be met by using a workbook referencing a query result in another sheet.
But I not sure can a workbook allow for drilldown without messing up the excel formulas set in the cells like KF columns or header?
I am not using hierarchy in the rows. Just plain characteristics.
The columns are FY outside the KF Columns which can vary in number of columns depending on how many FY entered by user.
Hope to get some clues.
