I am curious to know if one could create a "management overview" workbook containing live links to various other workbooks. As such, the values on the single management workbook would change immediately after values were changed in any linked supporting workbooks. The tricky part would be that the values would need to be changing on a live basis while both workbooks are open. In effect, someone watching the management worksheet could view changes in a near real time basis and see how the overall values changed while employees entered data on the supporting workbooks. Is excel 2013 capable of this or is a specialty tracking software required?
