Report elements can use the same data set if the data set returns the right amount and type of data for each element. For example, two tables can use the same data set if one table displays detailed data, and the other table displays the summary version of the same data. In the second report shown in Figure 19‑1, the two summary tables and the sales detail table use data from the same data set. Each report element that uses data from a single data set can sort, group, filter, or aggregate its data differently. For example, one table can sort sales data by country, and another table can sort the same data by sales total.
