Hello Ram, yes, I will look into it!

EDIT: Hi again Ram, I can't really see which are the fails. Could you provide the direct link to the workflow instance that generates the fail?

@kamilsi, @ramiromagno, thanks so much for your review and suggestions. Please note that I addressed couple of them in this PR and also opened https://github.com/pharmaverse/sdtm.oak/issues/38 to address the remaining in the future. I also added example SDTM CM datasets.

Please review/approve so that Ramiro can kindly proceed with derive implementation.
