In ASOsamp .Sample, adding a child member under Systems in the All Merchandise hierarchy increases the number of children under Systems to three, crossing the power of 2 boundary. When the outline is saved, Essbase performs a full outline restructure.
However, adding a child member under Computers and Peripherals increases the number of children under Computers and Peripherals from three to four. Adding a fourth child, which must be added after the existing members, does not cross the boundary of 2 or 4. The child must be added after existing members. When the outline is saved, Essbase performs a light restructure.
