In the SDTM TV dataset, the variable ARMCD exists but no ARM variable exists. The ARM variable in the study define.xml file has been listed as a key. However, when the OpenCDISC Validator executes using both SDTM + define.xml, no errors are fired to indicate this problem. Maybe the errors SD0054, SD0058, or SD0059 should have fired? Not sure if maybe another rule should have fired?
