Unconstrained Plan- Firm POs

Hello All,

We are running unconstrained ASCP plan. We need all the open Purchase orders and work orders to be considered as Firm by ASCP and not suggest reschedule-ins/outs. I do realize there are Firm check boxes on PO and WO,but that

requires firming each of them.

Instead, can we make sure on the planning side, to consider all open POs/WOs to be firm.  I tested with the profiles :MSO: Firm Purchase Orders Within Time Fence and MSO: Firm Work Orders/Operations Within Time Fence

but those dont seem to have any impact.

Thanks

Sri
