説明
This property can be set to True only if the AreMemberKeysUnique property is set to True for all of the levels in the dimension.
This property can be used in two situations:
When you know that the position of a member (and that of the children of the member) may move within a dimension hierarchy. You can make the method for generating unique names more consistent by using this property to determine whether or not a member, name, or key is guaranteed to be unique within the dimension (or level).
When you need to improve server performance. Data can be more easily validated if you use this property to inform the server that a dimension key is not unique within the dimension or level.
使用例
' Assume the existence of a database dimension named dsoDim.
dsoDim.AreMemberKeysUnique = True
