Pasting action with due date

I want to create an action with due date and I can’t manage to do it.

PMT-01 100$ @1/11/2016
copy from another program and pasting in omnifocus result in:
PMT-01 100$
with no due date

You want to use task paper format. There is a post at, but the easiest way to get started is to use Copy as Taskpaper on an item in OmniFocus then paste into a text editor to see the syntax.
