ATP check is not triggerred
We met an issue when user changed the sales order quantity, the confirmed qty is not changed.
The senario is like that:
sales order A created on Sep 1st, qty 1000pc, and confirmed qty 1000pc. the stock is 1501pc, there is no other sales order in the plant.
on sep 2nd sales order A was changed the qty to 1500 pc, but the cofirmed qty was still 1000pc, it seems ATP wasn't be triggerred.
user didn't checked the schedule line and create a delivery next day with qty of 1501pc, and then goods issue.
Could anyone help to check why the confirmed qty wasn't be changed untill now. and the delivery can be created? Thanks bey much.
