PROC CDISC performs the following checks on domain content of the source:

Verifies that all required variables are present in the DATA set Reports as an error any variables in the data set that are not defined in the domain Reports a warning for any EXPECTED domain variables that are not in the data set

Notes any permitted domain variables that are not in the data set Verifies that all domain variables are of the expected data TYPE and proper length Detects any domain variables that are assigned a controlled terminology specification by the domain and do not have a format assigned to them.

The PROCEDURE also performs the following checks on domain data content of the source on a per observation basis:

Verifies that all required variable fields do not contain missing values Detects occurrences of expected variable fields that contain missing values Detects the conformance of all ISO-8601 specification assigned values; including date, time, date time, duration, and interval types Notes correctness of yes/no and yes/no/null RESPONSES
