I am facing this issue, kindly help me out.
If there is not sufficient stock in plant the order has to set to be in reason for rejection automatically.
In general scenario if there is no stock (sufficient ) in plant, system can't confirm order, then we can keep reason for rejection manually for that order.
But here we are not processing availability check at sales order level.
We are doning in AFS methodology that is after sales order we execute allocation run here the system performs availability.
Every day we use to create thousands of order so we can't keep manually for each and every order reason for rejection when there is sufficient stock in plant.
Thanks in advance
