If URL has sysparm_device parameter added and if it does not have any valid values then it redirects to UI11Description<!-- div.margin { padding: 10px 40px 40px 30px; } table.tocTable { border: 1px solid; border-color: #e0e0e0; background-color: #fff; } .title { color: #d1232b; font-weight: normal; font-size: 28px; } h1 { color: #d1232b; font-weight: normal; font-size: 21px; margin-bottom: -5px; } h2 { color: #646464; font-weight: bold; font-size: 18px; } h3 { color: #000000; font-weight: bold; font-size: 16px; } h4 { color: #666666; font-weight: bold; font-size: 15px; } h5 { color: #000000; font-weight: bold; font-size: 13px; } h6 { color: #000000; font-weight: bold; font-size:14px; } ul { margin-left: 0; } li { padding-left: 1em; } hr { border-top-width: 1px; border-top-style: solid; border-top-color: #cccccc; } --> The sysparm_device parameter is used when you would like to change different UI for ex UI15, UI16, Mobile, tablet or printer mode etc on your instance. Example: Following are valid inputs for this parameter doctype = UI14, UI15, UI16 for ex. https://<instance>.service-now.com/navpage.do?sysparm_device=doctypetablet = Tablet m = $m.do Mobileprint = Printer friendly If sysparm_device has any other value then it goes to UI11/Legacy. For ex. https://<instance>.service-now.com/navpage.do?sysparm_device=docs ResolutionThis is intended behavior as per design.
