May I know why don’t we have any data for source_to_concept_map table in vocab files?
Currently our source_to_concept_map table is empty. Is it usually empty?
Is it only used to upload our custom concepts or we expected to see some source_to_concept mappings for OMOP concepts?
Am not sure I deleted the data by mistake. Where can I find the data for source_to_concept_map table if at all it exists else am I right to understand that it is only for our custom concepts?
Can someone shed some light on this?
