You can edit a traceability event after submitting it, but only events your own Participant Organisation created. You do this from the specimen detail screen in View Coral on the Coral Traceability Solution (CTS) mobile app. Open the specimen first.
To open a specimen, see How do I view coral details by scanning a tag?
Find an editable event
On the specimen detail screen, look at the Traceability events list. An edit (pencil) icon appears only next to events your Participant Organisation created. Events created by other organisations have no edit icon and cannot be edited.
Edit and save
Tap the edit (pencil) icon next to the event, change the data, and save. The edited data is saved to the CTS, you return to the specimen detail screen, and the traceability event reflects the updated data.
