AFS rejection code J0

Hello,

In AFS we have standard functionality to apply rejection code J0 to sales order item if quantity is not available during ATP. This is mostly working fine for us but we recently identified a bug.

Suppose anything is changed in the sales order like requested delivery date, delivery priority etc then system is applying J0 rejection code even though we have stock available. If we manually remove J0 and run ATP in VA02 then system confirms the quantity. I am not sure in what case this is happening so I am not able to replicate the bug.

Has anyone else using AFS come across this bug?

Thanks.
