Hi Umesh, I cannot reproduce your case. A sample data would be helpful for diagnostics. My email is **sergiy at opencdisc dot org** Please ensure that you do not have any **leading space character in DSSTDTC variable values**. It looks like in your example a row #4 in DS domain includes this programming error. Check for SD1021 messages in DS domain. Regards, Sergiy ---

Can someone in the group provide me a solution to the issue described below?Here’s the issue: **DS Domain** 1. SubjectID EPOCH DSSTDTC 2. xx-xxx SCREENING 2016-03-31T10:36 3. xx-xxx TREATMENT 2016-05-05 4. xx-xxx TREATMENT **2016-07-28** **EX Domain:** 1. SubjectID EPOCH EXENDTC 2. xx-xxx RUN-IN 2016-05-05 3. xx-xxx TREATMENT **2016-07-28** As we can see the subject EXENDTC is less than or equal to the latest disposition date,the open CDISC validator fires FDAC050 message in the report.Not sure why it is doing only for selected subjects. There are some other subjects with the exposure end date that is equal to or less than the max(dsstdtc) but it’s not firing FDAC050 for those subjects.I wonder if this logic to compare the two dates has not been implemented correctly.Any help regarding this issue is appreciated.
