Hmmmm.....

The perldoc for Transaction_Overlay says:

Create

       Create a new transaction.

       This routine should _never_ be called anything other Than
       RT::Ticket. It should not be called from client code. Ever. Not
       ever. If you do this, we will hunt you down. and break your
       kneecaps. Then the unpleasant stuff will start.

Maybe I should be a bit clearer. 

My scrip creates a ticket using a template. That's all.

The reason the idea of executing the scrip from code occurred
to me is that I can't figure out how to pass the template parameters
to my $Ticket-Create() call, like Parents, and DependsOn, things
like that.

Do you see what I mean? The entire "action" of the scrip is already
contained in the scrip itself and the template associated with it.
It makes sense for it to stay there. 

I just want to execute it from code.

But how?

Thanks,

Jens
