Could it be the value format not serial ???

[ashrafalzyoud]

i need the user enter the value but not serial like (100,155,170)

For instance I need to create Custom Field storing an OrderID (entered manually) and I want it to be unique across all tickets. Is there a way to achieve it?

Hi,

Not really, this plugin provide automatically increment numbers, as I see.

      if value.present?
        value.next
      else
        generate_first_value(custom_field, datetime)
      end
