ATP date vs actual fulfillment date

Summary:

We have an implementation where order/demand is created external to Oracle, integrated into Order Management/GOP , and collected into Planning to create Purchase Orders. We run Supply Plan daily with autorelease to create purchase orders based on demand and lead time set for items.

We have an issue where for items when ATP is checked, it will give an incorrect date because the delay in running the plan and creating the purchase order is not taken into account. Is there any way to accommodate this into the ATP calculation logic?
