Question about RMA with several lines

Hello,

I'm looking for information about RMA with several lines. I enter a RMA in P400511 with several lines, all of them with "Last disposition" of PLR. My questions are:

- Is it possible to update all the lines to the same "Last disposition" code at the same time??

- If I use the option of creating a credit order for all the lines, is it possible to create only one credit order number for all of them? I mean, one credit order for one RMA, and not different credit orders by line.

I would also like to know if it is possible to receive an RMA globally, and not line by line. I'm almost sure that it is not posible, but maybe there's a workaround to do this.
