10.4 Group Report with Two Break Groups

Figure 10–10 Group left report output with two break groups The figure above shows a further modification of your group left report. In this version, DEPARTMENT_ID prints only once for each department. JOB_ID also prints only once when more than one employee in a department has the same job. Both columns are now in separate break groups and DEPARTMENT_ID is in the higher group. Hence, it does not repeat for each unique value of JOB_ID within a department any more. Concepts ■ You can also create reports that include multiple break groups and assign one or more columns to each break group. ■ You will further modify the data model to include two break groups: G_ DEPARTMENT_ID and G_JOB_ID. ■ After changing the data model, redefault the layout to incorporate your changes, then specify the format mask again. To see a sample group left report with two break groups, open the examples folder named break, then open the Oracle Reports example named grp_lft2.rdf. For details on how to access it, see Accessing the Example Reports in the Preface.
