Supplier log on Supply portal to confirm PO
eg: PO#001/Line1/Rel 1 - PO qty =3000, with wanted delivery date 4/1/2022, from supplier side, they only can 1000 on 4/1/2022, 2000 on 4/15/2022,
the expected result is, when supplier change PO qty to 1000 and write down date as 4/1/2022 in PO#001/line1/rel 1, then another PO line with same PO#001/Line1/rel2 will be popped up with PO Qty=2000 (the rest of 3000 after 4/1/2022, price and other message is the same as original PO status), then supplier write down date as 4/15/2022.
how to make this happen?
please advice
Thanks
