Good morning, We would like to share with you a doubt, and we would appreciate if you could read and answer us. Currently we have a file titled: "Imagen PatientID 9358340 PatientName Milagros ReasonForStudy 350290 InstitutionName 350290  StudyDate 20220927.xml" , in which we have the following InstitutionName:     <DicomAttribute keyword="InstitutionName" tag="00080080" vr="LO">         <Value number="1">350290</Value>     </DicomAttribute> ![](/sites/default/files/inline/images/images/imagen(302).png) Once we generate the DICOM file using the command  from the tool named "xml2dcm" inside the DICOM simulator package dcm4che: ./xml2dcm -x "Imagen PatientID 9358340 PatientName Milagros ReasonForStudy 350290 InstitutionName 350290  StudyDate 20220927.xml" -o "Imagen PatientID 9358340 PatientName Milagros ReasonForStudy 350290 InstitutionName 350290  StudyDate 20220927.dcm"   We obtain the image in a .dcm file. When we open it in the viewer, it is shown InstitutionName = 350290 ![](/sites/default/files/inline/images/images/imagen(303).png)   However, when we request from the ESB with HealthShare 2020 version, using PatientName = "Milagros" , the destination system which is being simulated from the dcm4che DICOM simulator, responds with this image indicating the InstitutionName without data, i.e., empty: Request: ![](/sites/default/files/inline/images/images/imagen(304).png) # <c>DataSet</c>
