It would be more efficient and make the "Batch Add Material" more usable if there was a column to adjust the margin and a button to set the purchase order to "Mark As Placed".
Right now you can add multiple parts in a single screen but then you have to go back into every individual line to adjust the mark up.
Also you have to leave the work order, go into "Purchases", search the "Purchase Orders" to find the one that was just created, go into that purchase order and "Mark As Placed", go back into the work order/purchases tab and receive the parts.
