Error updating statistics from Admin screen, and system not working actually

Oh, and if you don’t have LAST_UPDATED at all, you can just map it to your RPT_DATE / ENCOUNTER_DATE in the DOC_FIELD_EMR_INTENT table. Something like:

update DOC_FIELD_EMR_INTENT 
   set SOLR_FIELD_NAME = 'RPT_DATE' 
 where NAME = 'LAST_UPDATED'
