Hi Team,

We are getting AD0018 : variable label mismatch between dataset and ADaM standard for AENDTM and ASTDTM.

The labels are defined as below currently.


AENDTM  : Analysis End Datetime

ASTDTM   : Analysis Start Datetime


Please suggest why this error is coming, we  have checked the ADaM IG and the current naming is the same as it in guideline


Thank you,

Hi Rajasekhar, 

According CDISC documentation, Labels for ASTDTM variable are

  • "Analysis End Datetime" in BDS
  • "Analysis End Date/Time" in OCCDS 

Kind Regards,
