Deletion of Transportation lanes with MASSD

Dear Experts,

I'm trying to delete plants in APO and the actions I have to perform are clear, but HOW I do it is something else....

In transaction MASSD I can select OBJECT: Lane Transportation Lane and I make my selection.

Below I select a Component e.g. Header data.

When I execute I got a list but I don't know how to delete all the Transportation lanes involved!

thanks
