WM Cross Docking


i want to ask about cross docking. anyone can explain to me how to config cross docking in WM ? because ii have searched in about cross docking configuration, in this site :


it said to "Maintained warehouse level settings in Customizing for Logistics Execution ® Cross-Docking ® Maintain Warehouse Level Settings". But when i enter to SPRO, i find option Cross Docking, but i never found it.

Can anyone help me please ?? Thanks before for your advice.
