Thanks for the reply. I have another requirement like If my list of document has {Horror, Romance,Fantasy,Mystery} and I chose Horror from the picker , for the next time when I search for another genre, I don't want Horror in the list. I asked some suggestions and tried using difference and remove options , Neither of it is working. Can you help me with this.

Agreed! I just referenced the code in the question & missed this one.

FYI you shouldn't have to save into local!documents twice like this. That's what "save!value" is for --

saveInto: {
  a!save(
    local!documents,
    union(save!value, save!value)
  )
}

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.
