(Solved) Rma - What To Do With The Order - What Does It Mean?

Dear community,
we are currently in the process of dealing with returns.
When vendors want to process a return, 3 different options appear as a radio group in the “Actions” tab.

  • - Recalculate order
  • - Set the new order total manually
  • - Don’t recalculate order

Nowhere in the documentation are these 3 options explained in detail and what exactly they do.
Does anyone know what they do and how they differ?

It would be great if someone could explain them to us, because we really can’t find anything about it.
Thanks a lot in advance!
Kind regards,
