Hi Pierre,
SDTM IG 3.1.x says (#6.3.5.1 on page 147) that “4. The following Qualifiers would not generally be used in QS: …, --METHOD, …”. Based on this text the Validator considers QSMETHOD as “Not Recommended” variable.
In IG version 3.2 QSMETHOD variable was removed from the list and its new P21 Core attribute should be “Model Permissible”. However, it is still unchanged in SDTM IG 3.2 specifications of P21 Validator. This bug will be fixed in the next release.
I am not sure how to handle specifications for older versions of SDTM. Most likely we will also use a “Model Permissible” attribute value as a correction of obvious error/inconsistency in early versions of SDTM standard.
Thank you for reporting this issue!
Kind Regards,
Sergiy
