10 Additional information for Storage Commitment ExPACS after reciving N-ACTION (from Storage Commitment Push Model) will get a list of SOP instance and check if they are accessible under repository. Next it will send N-EVENT-REPORT-RQ to specific AE, from which it recive N-ACTION (in this message there will be confirmation for received instance).
