Hello @sgtrun,
I cannot really help with that, sorry. Perhaps you can share this question with SAS Technical Support, which seems to be the appropiate SAS team to answer the question.
The only thing I can do to perhaps help a bit is to share this other link https://support.sas.com/rnd/emi/SASEnvMgr/EVSAF/Report_Center_Report_Listings.pdf
Maybe contrasting the data on that table and how those reports are created, you can acquire knowledge on the nature of the data of the artifacts SAS dataset.
