Stock APLETT01.rpt customization

This is hopefully a simple request. Trying to use the stock APLETT01.rpt form and have it filter out all "inactive" vendors. Focusing on the {APVEN.SWACTV}=1 field as a record selection but cannot get it to filter. I assume it has to do with the APSLVEN table as the grouping.

Surely this is a common edit to this report.
