Hi Chris,
We had some question on the functionality here a little while back. We are on 10.1.600, so I’m not sure if same in your version. Anyway, we found that if a “Split” value greater than 0 (100 typical percent for us) was entered on the quote People/Salespersons/Detail tab (screenshot below) then the sales rep/commission came across onto the sales order. Based on this, I think you might want to ensure that you actually need this bpm. Perhaps the system already does what you need when split is completed.
