Hi Bessie,
Your example with ACTARMCD=“UNPLAN” is actually about SD2002 check, which use TA domain as a look-up source for valid ACTARMCD values.
SD2236 is a data quality checks, rather than standard compliance rule. The check’s purpose is to report subjects which received other than Planned (ARMCD) treatment. ACTARMCD does not have to be the same as ARMCD. However it is expected result if there is no Protocol Violations in the study conduct process.
Kind Regards,
Sergiy
