You could also include some additional formatting like marking the quantity red when it is below a certain value and marking it green when it is above a certain value. This can be achieved by right clicking of the Quantity field on the report, selecting Format, selecting the Font tab, clicking on the x-2 symbol next to Color, and specifying a condition like :
If {Sales.Qty} > 50 Then crGreen
Else If {Sales.Qty} < 50 Then crRed
Else
crBlack
Different reports would have different requirements. Reports without any Groups or with just one Group could be much simpler. As the number of Groups increase, the report creation could get more complicated. The important thing to remember here is that using a combination of the Header and Footer, Formulas and Conditional Formatting will give you total control over designing the report to your specific requirement.
