Automatic Extract Article from Ticket

I am a newbie of RT/RTFM and I’m trying to create a scrip that when a
Ticket is created (gui o e-mail ), automatically creates an item in

I have the class associated to the Queue and only one custom Field (
body of the article )
Some have already had this experience?

RTv3.4.5 RTFM 2.2.0

Thanks in advance for your help
