The way we do this here (in the case of a free replacement or rework at their expense) is to delete the DMR-REJ action (and any lingering unused debit memo) and then do a DMR-STK transaction.
My former boss (then plant controller) came up with that and he really liked its simplicity.
Big warning: we later found that there is a bug in Epicor if you do this across a period.
For reference, this is how the GL works with it all (given our GL code setup - substitute your own):
My note at the end kind of alludes to the bug. I think I was on to something before I fully understood the bug. What it really means is, in the same period, the RTV rejections seem to disappear from the GL.
