A PO is grouped by
supplier. If the supplier has been assigned 3 lines, then the PO will contain 3
lines for that supplier. If you have 2 suppliers, and each has been awarded 2
lines, then you will have 2 PO documents for each supplier containing 2 lines
each. Consider that if you have approved a line and a PO has been created, and
a couple of day later you approve other line on the same PO for the same
supplier the PO document will be updated. PO’s are group by supplier.
