Back to Back Orders and ASCP

Hello,

We are on 12.2.6 and implementing back to back orders where the item is a Buy item and ATO enabled and sales order will generate a Purchase Req and eventually a PO .We also want to use user defined safety stock for these items.

Have some questions in this regard:

1.If we run ASCP plan for such items as above is it likely that ASCP may suggest planned orders for the SO that has been entered but not yet converted into a Req?

2.If the SO has generated a Req and or a PO , can ASCP use that to peg against the safety stock demand instead of the SO that generated it and generate planned orders for the SO?Basically we want that ASCP must generate planned orders to meet the safety stock demand in this case and not use PR or PO that was created from the SO to meet that demand.
