The Table Detail Grouping smart panel gives you access to four pages. 
Detail grouping is useful when you do not want to repeat values within the details. When a detail grouping is set, the value repeats for each distinct result of the grouping expression instead of for each row of data. For example, if you use the Customers table of the NorthWind database to create a list of countries without setting the details grouping, each country is listed as many times as there are customers in that country. If you set the details grouping to =Fields!Country.Value each country is listed only once.

Note: If the detail grouping expression you use results in a value that is distinct for every row of data, a customer number for example, you will see no difference in the results. |
