As Carlos said, ca you give your scenario and movement types. Then we can guide.
Right now, If you do not want neither TR nor Posting Change, In the IM-WM interfaces, when you are determining your WM movement type, you will have the option of TR or Posting Change. I would suggest you to tick none. So that, you wont get neither TR nor Posting Change. Then, you no need to create TO and Confirm.
Before taking it confirm, If you can present your scenario, we can help you better.
