我可以在Crystal Reports中进行两级链接吗?

假设我有三个列表:部门、部门和组。部门由部门组成,部门又由小组组成。

部门将部门ID作为外键。这些组将分区ID作为外键。

Department 1
    Division 1A
        Group 1A-i
        Group 1A-ii
        Group 1A-iii
    Division 1B
        Group 1B-i
        Group 1B-ii
        Group 1B-iii
    Division 1C
        Group 1C-i
        Group 1C-ii
        Group 1C-iii
Department 2
    Division 2A
        Group 2A-i
        Group 2A-ii
        Group 2A-iii
    Division 2B
        Group 2B-i
        Group 2B-ii
        Group 2B-iii
    Division 2C
        Group 2C-i
        Group 2C-ii
        Group 2C-iii
Department 3
    Division 3A
        Group 3A-i
        Group 3A-ii
        Group 3A-iii
    Division 3B
        Group 3B-i
        Group 3B-ii
        Group 3B-iii
    Division 3C
        Group 3C-i
        Group 3C-ii
        Group 3C-iii

I know how to use a subreport 在Crystal Reports(VB.NET和Visual Studio 2005)中,让我进入部门级别:

Department 1
    Division 1A
    Division 1B
    Division 1C
Department 2
    Division 2A
    Division 2B
    Division 2C
Department 3
    Division 3A
    Division 3B
    Division 3C

但是自从 I can't include a subreport within a subreport

提前谢谢!
