Client Application Analysis drilldown Unit of Work tab

The Unit of Work tab on the Client Application Analysis drilldown provides details and statistics about the currently executing unit of work. When the execution time for an application’s current unit of work is high ( Curr Uow Sec column in the list grid), use this tab to investigate this unit of work.
