My question is about calculation within EDC (e.g. BMI). In Define-XML V2.1 type is "derived" and source is "sponsor". In addition should we flag these EDC calculations with DRVFL="Y" ? Or DRVFL is only populated to Y when a new record is added comparing with the source.
Thanks for your help,
Thank you for the reply.
I send also the question to the LinkedIn "SDTM Experts".

My way (5 cents) ...
If the derivation is done in the EDC system and the investigator can inspect the result, then I do not set DRVFL to "Y", i.e. I consider the data point as "captured".
If the derivation is however done during SDTM generation, I definitely set DRVFL=Y. I presume this is the same as saying "when a record is added comparing with the source".
BTW, this is a question that is better asked at e.g. the LinkedIn "SDTM Experts" forum (https://www.linkedin.com/groups/2758697/).
