ATO availibilty check

Hi,

How does the ATP check work in the assemble to order via process order work ? I mean in a regiular sales order u have the ATP check A or AE running depending upon the requirement class (if it is MTO or MTS). However in an ATO scenario where the process order is automatically created via the sales order, which ATP runs ? Is it the A/AE one at sales order level or is it the PP checking rule running at process order creation and release level ? Also in the requirement class for ATO whihc is KMFA there is a checkbox for component availibilty. What purpose does it serve ? If I deselect it which means there should be no ATP running for components there is ATP running in the process order and I get a missing parts list. Why is the system doing this ? Dosent that indicator switch on/off the component availibilty ?

Thanks
