The name refers to the dataset provided by the source_datasets parameter

filter
An unquoted condition for selecting the observations from
dataset which are events or possible censoring time points.
date
A variable or expression providing the date of the event or
censoring. A date, or a datetime can be specified. An unquoted symbol or

Refer to derive_vars_dt() or convert_dtc_to_dt() to impute and derive a
date from a date character vector to a date object.

A named list returned by exprs() defining the variables
to be set for the event or censoring, e.g. exprs(EVENTDESC = "DEATH", SRCDOM = "ADSL", SRCVAR = "DTHDT"). The values must be a symbol, a
