how to generate and view pdf on single click

Try to use Record Action for it. The process would generate the PDF and show the pdf as well. Enable the activity chaining as well.

When you enable process chaining up to the node that creates the PDF, you can fetch the ID of the generated document from your UI. Feed that into a document viewer.

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) */
