Then an aStorage Commit Request is triggered. Depending on configuration, the syngo <strong>MR</strong> product<strong>DICOM</strong> application will keep the association open for responses with a configurable time-out,or closes the association and expects responses on a different association that has to beestablishes by the remote Storage Commitment SCP.The commitment status derived from the related trigger response will be indicated in therelated Status Flags of the related entity. It is possible to create triggers (“auto rules”) from thisevent.The Transaction UIDs of the pending commitment request are kept “open” for a configurableamount in time (default: 1h). If the “open time” for a pending commitment request has elapsedw/o a related response from the provider, the Transaction UID is removed and the relatedentities are indicated as “commit failed”.In any case, commitment will only be requested for previously and successfully sent images.© <strong>Siemens</strong> AG, Healthcare, 2009 Rev. 9.0 Page 31 of 149
