Available to Promise (ATP)

Hi all,

I am using AX 2009. I have set ATP Fence date to 10 days.

I have an available physical on-hand of 100.

I created a sales order (say, SO1) for qty=100 and registered the total qty. I have now physical reserved of 100 and available physical of 0.

I created another order , SO2, for qty=1 (for same item and dimension) and run simulate the delivery dates. I am expecting that it will tell me I don’t have on-hand because all quantities are reserved for SO1, but it did not.

Why is this so ?

If this is default behavior, how can I configure it such that it will consider physically reserved quantities?
