Have you populated Observation Period table? According to the docs (ETL conventions and answer #3here), each Person needs to have at least one observation period, which should represent time intervals with a high capture rate of clinical events.
Observation treemap in ATLAS uses data collected by analyses 800 and 801 from Achilles, both of which require the events to fall into a valid observation period for the patient. This is probably the reason why you are able to see the report for Person table but all others show ‘no data’.
Thank you so much for your help. No, since the data are from survey/registry data, I did not realize that the an observation period is required for the CDM.
