On the Purchase Management Journal, it is possible to split the line directly and it will go back to the purchase order.
For example, I have this line and I want to split it into a delivery of 5 and a confirmed receipt date, new direct unit cost at 0.06. Go to the related function and split the purchase order line. Now I have two lines. I split the original line with 5 with a new direct cost and it puts the rest, the 15, on a new line and suggesting that the new requested cost would be 0.06 as well. But actually on this one it could be different. It could be that we could get this one because maybe it’s a later delivery. It could be we could get this for 0.05 at a later date. Now I can just accept the lines and go to the purchase order and view the changes.
