a!gridColumn( label: "Doc View", value: a!recordActionField( actions: { a!recordActionItem( action: 'recordType!{recordTypeName.action.viewDocument', identifier: fv!identifier ) }, style: "LINKS", display: "ICON", openActionsIn: "DIALOG", align: "CENTER" ), align: "CENTER", width: "1X" ) 
 
 Hi, Try to create an action in record and call it , as mentioned above.When you click that icon you can open your doc with one click 
 { a!sectionLayout( label: document(ri!document, "name"), labelSize: "MEDIUM_PLUS", contents: { a!documentViewerField(document: ri!document) }, divider: "ABOVE", showWhen: a!isNotNullOrEmpty(ri!document) ) } 
 /*In record action attach a process model -> in that PM give only one UI -> and that UI contains above bold code(pass doc Id as ruleinput to UI) */
