This dimension setup decides how issues are grouped based on dimensions

But just this setup wouldn’t be enough to achieve grouping when you run the scheduling engine.

Make sure you also setup the “Coverage code” in the Item Coverage group to “Period”. If  this setup is not done then you will still find issues getting created individually or based on Min Max
