Filter to choose Appropriate Supplemental AE Records for Multiple Causalities or Actions

The Filter to Choose Appropriate Supplemental AE Records for Multiple Causalities or Actions field is an optional parameter that enables you to filter rows from the DS data set to choose the appropriate supplemental AE records to define relationships or actions for multiple drugs when either AEREL = "MULTIPLE" or AEACN = "MULTIPLE". Subsetting can use only USUBJID, IDVARVAL, QNAM, QLABEL, QVAL. This where statement is in addition to an initial subsetting of records where QNAM begins with either "REL" or "AEREL" to identify records for causality or "ACN" or "AEACN" to identify records for action taken.
