Hi Letizia, Thank you for including a screenshot of AD0018 firing. I confirmed with our team this is a known issue with these three labels and will be fixed in a future engine release. For now, the issue can be explained. Thanks, Matt ---

Hi, I get the following error: Variable label mismatch between dataset and ADaM standard for COHORT, NCAXFL and NRRLT variables in my ADNCA dataset. I have used the labels provided in the “Analysis Data Model Implementation Guide for Non-compartmental Analysis Input Data” document, but I keep receiving an error. Am I possibly making a mistake in implementing the labels? I would appreciate any guidance you can provide or if we could further discuss the issue.
