segment value security for self service receiving in ERP Oracle Cloud

segment value security is enabled, and user does not have the particular cost center access but still able to perform self service receiving for purchase order for which the charge code contains restricted cost center.

For example, segment value security is enabled and there is a purchase order with charge code that contain 0001 cost center in it. User does not have access for 0001 cost center but still able to perform self service receiving for this purchase order.

can some one please confirm if segment value security is not applicable for self service receiving?

If we want the user to receive only the purchase order for specific cost center then how we can achieve this requirement?
