I encounter an issue with ATP ECC, I'm able to confirm more pieces as it's possible.
I'm explaining : I order 70 pieces and only 60 pieces are available. then the ATP popup is displayed and proposes
a) either "one time delivery for 60 pieces"
b) or a delivery proposal that it's exactly the same as point (a) bcz we don't take into account the expected stock (PO, Inbound Deliveries).
-> When I try to change "60 pieces by 65 pieces" in the line of "One time delivery", I get the message "The confirmed quantity - 60,000 PC - can only be reduced". and it's normal.
-> When I try to change "60 pieces by 65 pieces" in the line "delivery proposal", I can do it without having any issues ! Moreover, I can confirm and I get in the procurement tab of my item : 65 pieces confirmed!
infact, up to 149,999 pieces, I'm able to confirm my sales order item, once above that, I get the error message "On the 09.03.2017, only 60,0000 PC available".
REMARK : CO06, MD04 are well aligned with 60 pieces available. in my example, I take material with no expected stock, not other requirement !
I tried with several materials, several plants and I always get this issue.
