Assume a three column database showing Site ID, Customer, Status and Requested Date. On the same site ID, the same customer may have different status on different dates. In such a scenario, one may want to know the farthest/latest requested date and its corresponding status for all unique combinations of Site ID and Customer.
I initially attempted to solve this problem by using a pivot table but the pivot output was incorrect. The pivot was returning the farthest/latest date for all status’ of a particular Site ID and Customer. Ideally, it should show only the farthest/latest date and its corresponding status for a particular Site ID and Customer. Therefore, for a particular Site ID and Customer combination, only one row should show up in the final output. Therefore, the Pivot Table solution did not work.

Depending upon the version of MS Excel which you are using, there could be two ways to solve this problem
Solution for MS Excel 2010 and higher versions
If you are using the Power Query add-in, then a few simple steps (no formulas at all) can solve this problem. The result will be dynamic and refreshable (just as in a Pivot Table)
