Hi,

In my recent experience, OpenCDISC flagged it in a dataset I validated yesterday, but flagged it as a Warning, not as an Error. I was using the straight 3.1.2 sdtm validator version.

Hi Jim,

Your data issue is expected to be detected by a SD0040 check. I used your example for testing and it works well. Could you provide more details what is wrong?

Thanks,

Sergiy

SD0040 check

Message: “Inconsistent value for --TEST within --TESTCD”

Hi all,

I thought that there was an error check for the uniqueness of TEST/TESTCD. (They had to match 1-1)

We had a study with the following error, and we I cannot figure out why we didn’t get an error with OpenCDISC Validator.

I understand in they example below that UNIT1/UNIT2 don’t belong as part of the TESTCD.

However, I don’t understand why we didn’t get this an error in the OpenCDISC Validator Report.

xxTEST xxTESTCD

RADACT Total Radioactivity Unit1

RADACT Total Radioactivity Unit2

Thanks,
