Mass deletion of Transportation lanes

Hi ,

We have a req. to perform mass deletion of Tlane. Do I need to go inside each and every Tlane and mark it for deletion and then run the mass deletion T code???

Or is there way to perform this using any tables??

Also we need to check the orders linked to the Tlane, I am able to get the order details using WUF, how can we delete all the orders using some table?? i would need to delete PR's STR, Planned orders...

thanks
