Hi Community,

I can see there is no column for performer and category in obs table of openmrs , So If I want to use Observation endpoint of fhir2 module of openmrs and want to save performer and category in openmrs db, whats the approach for that ? where i need to change for this?

I have core, rest and fhir2 module locally running.
