Cohort table listed in CDM V.5.3

[solmazeradat]

Hi,

I had a question about Rabbit In A Hat. I noticed that the table Cohort under vocabulary tables is listed when selecting V5.3 (See screenshot below)

From the documentation cdmV5.3 this table is not listed, however, does appear in V5.4.

Many thanks,
Solmaz

Defining a cohort is typically an operation that is done after the ETL is complete. Do you have a 'use case' where the cohort is filled from the source data?

My question was more around why the table Cohort appears in the RabbitInAHat tool when setting the target database to V5.3? From reading the documentation it looks like the Cohort table was added in V.5.4.

@solmazeradat Indeed, this inconsistent, only cohort_definition should exist in v5.3.

That said, the cohort (or cohort_definition) table is typically not populated during ETL. Does the presence of the cohort table in RiaH break a workflow for you?

Hi @MaximMoinat - no it does not break anything for us.
