When I run Achilles, I get the error listed above from check 1900. Looking through the SQL under inst/sql/sql_server/analyses/1900.sql, it looks like the issue comes from lines 64-71 shown below.
When I looked at the OMOP CDM requirements, the tables visit_occurence and visit_detail don’t seem to have the column admitting_source_value. These tables do have admitted_from_source_value, so I’m not certain if that’s the column that is meant. This all assumes that I’m reading the SQL right, and if I am, it looks like there’s a bug.
