Hierarchical filtering in tableau

 Selecting  the values in one filter if it is effecting in the other filter then such a kind of filtering is known as cascading filters this cascading filters are also known as hierarchical filters normally this cascading filters can be applied for the hierarchical data. if you  apply only relevant values on more than one filter means their filtering each other some time may resulting leads degrade the performance. so it is not good practice by applying only relevant values on two quick filters simultaneously at a time.
