Hello Vrinda,
Thanks for knowledge sharing info, I do understand as this tag is something unique i have identified and recently i have discovered that one of the Modality is specifically looking for 00020,0010 as Study Description.
Normally all modalities will fetch study description from 00321060 Requested Procedure Description in my experience, But i dont know this particular modality from GE is specifically looking for above tag as study description and if not sent from MWL then study description is showing as {undefined)
also i found area in arch ui where you can add new dicom tag - dcm4cheearc-device extension-archive extension-MWL attributes = I tried adding this tag and appears to valid, but not reflecting in edit mwl screen while adding new tag of "Add new attribute".
