You can delete members completely from the metadata, or you can remove members from parents and retain the members in the Member List tab. If you remove a member from its parent and the member has no other parent, it is considered an orphaned member in the Member List tab. Deleting a member completely from the hierarchy also deletes it from List View.
To delete or remove members:
Ensure that the Tree View tab is selected, and from the Metadata Item drop-down list, select a dimension.
Right-click and select a menu option:
Remove from parent to remove the member from its parent but retain the member in the Member List tab
Delete from dimension to delete the member from the dimension
