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. I ultimately solved this problem by using Advanced Filters.
