Ignore the Safety Stock at Internal Warehouse

We are using IR-ISO flows. IR is created from ASCP by the Planners against the safety stock setup at warehouse. Which further creates ISO and Work Order at manufacturing Plant. We are using ECC ASCP plans. There is a requirement from Business that the capacity for the resource should be blocked only when the ISO is created. Capacity should not be blocked for the safety stock at warehouse. When Planners release the planned order to create IR after that only Capacity at manufacturing plant should be blocked, Till that time the capacity should be available for external customers.

Any Profile/setup available to consider ISO as demand and not the safety stock at other internal Organization.
