Hi Kavya,

A union() in the save into might help to get distinct documents:

a!localVariables(
  local!documents,
  a!pickerFieldDocuments(
    label: "Document Picker",
    labelPosition: "ABOVE",
    folderFilter: tofolder(3244),
    value: local!documents,
    saveInto: {
      local!documents,
      a!save(
        local!documents,
        union(local!documents, local!documents)
      )
    },
    maxSelections: 3,
    validations: {}
  )
)

As far as I know, we cannot restrict the document picker to not show selected values again.
