If Show Assets is blank, on the asset grid page you cannot see an icon for Account Hierarchy and CPQ shows only assets from the current account.
If Show Assets set to Parents, Children, on the asset grid page you can see an icon for Account Hierarchy and CPQ shows assets from the current account as well as from Parent and Children.
