Hierarchy reports like CN41 , CN41N , is not either showing actual revenue or Actual revenue is added to Actual cost and the value is displayed as negative.
This is due to wrong configuration of value category. Different value categories should be created for cost and revenue so that the hierarchy report can segregate cost from revenue.
