When you pivot a group of members in an asymmetric report, Essbase keeps only unique members from dimensions that are not involved in the pivot.
To use the open Asymm.xls file to illustrate this point:
Using the right-mouse button, drag East to the cell below Qtr1.
Essbase combines the Product members into all unique members. For example, Root Beer is displayed once in the current view, instead of twice. Colas is displayed in East and West, instead of in only one market.
Essbase also removes the blank line between Product row groups. A pivot action eliminates rows or columns in which all cells are empty.
