title: Union being overridden in OBIEE
body: <p>I have used a 'Union' to combine two reports showing different dates. When I open the report on it's own it works fine with the two dates shown. However when I drill to the (union) report from another on the dashboard it only shows one date. Is there a dashboard filter that I may need to un apply or is there some other explanation!? I cannot seem to get the report to function as required from the drill. </p>
