The Order Management does not insert my promotional good with the note of a missing line type inform

Hi Pricing Specialists,

I need a modifier to create a new order line postion for a free item.

My issue is comparably with an buy one get one free topic. For this matter I've found a very good document in the database. My following setting is based on this doc.

I think my setup is quite good, but in the OM the system does not insert the line for the promotional good.

There only appear two notes:

1. A new line has been created fot item....

2. Please enter required information - line type

I have selected the line type for my first order position and for the second one, my promotional good, I can't select the line type, because there's no line insert.
