break up a hierarchy

Hi,

I have to break up a hierarchy (costcenter) to fulfill a report-requirement. Our system is Crystal Reports for Enterprise and my DataSoure is a BEx Query.

As default I get the hierarchy in this way from the Query:

L1                                                                                                                                                

        L2A                                                                                                                                      

                  L3A                                                                                                                        

                             CCT_AA 

                  L3B                                                                                                                            

                             CCT_BB 

        L2B                                                                                                                                      

                  L3C                                                                                                                         

                             CCT_CC 

                             CCT_DD 

Till this point everything is fine. Now, the requirement gives the following report-design per row:

1. Level                   2. Level                  3. Level                  CostCenter

L1                            L2A                         L3A                         CCT_AA

L1                            L2A                         L3B                         CCT_BB

L1                            L2B                         L3C                         CCT_CC

L1                            L2B                         L3C                         CCT_DD

Therefore I have to break up the costcenter-hierarchy to show the parent-nodes per costcenter and row. Does anybody has an Idea to get this aim?

Thanks
