Hello,
Always good to frame your question(s) a bit. SAS is used in all sectors, not just Pharma.
For someone working in a bank or in the automotive industry, your question is absolutely incomprehensible.
For me, too, actually. I think though it is about CDISC terminology
( https://www.cdisc.org/ --> Analysis Data Model Implementation Guide (ADaMIG) ).
I can't answer your question unfortunately, but someone else might?
But, is it a SAS question? Or just a data modelling question?
Are you using a SAS solution in the health and life sciences sphere, and you want to know how to do this with SAS?
I draw your attention to the fact that there are some boards in this communities site dedicated to "health" subjects :
