In large or complex dimension hierarchies, you can locate known dimension members to select neighboring members. This is a useful alternative to composing a search string for unknown members.
To find a known dimension member, right-click a dimension member in the Dimension Browser Selections list, and select Find In Tree.
In the Browse frame, the dimension hierarchy expands and the first instance of the selected member is highlighted. You can now select other members based on their relationship to the selected member.
