Drill down ( Collapsible Row ) Report in BEx query designer ?

Question

Dear Friends!
   I am supoosed to create a report drill down report for Purchasing History to be precise,  I know that we can have drill down feature using heirarchy but is it possible for Us to have PO & PO item heirarachy ? or any other way to do drill down reporting in SAP BEx Query designer ?
like my current report is : -
| Vendor | Purchasing Organisation | Purchasing Group | Plant | PO Number | Item | Material / Service | Description | .... ( keyfigures) |
Now I am supposed to create a report  in which
normal view
| Vendor | Purchasing Organisation | Purchasing Group | Plant | |> PO Number| .... ( keyfigures) | Payment |
drill down or collapsible view ( please consider the heading as data I am not talking about dynamically change of  headings ).
| Vendor | Purchasing Organisation | Purchasing Group | Plant | V PO Number | Item | Material / Service | Description | .... ( keyfigures) |
is there anyway to design the report in above mention manner ? you any input will be appreciated greatly.
Thank you so much!
Regards
Naim

Hi Naim,
usually we don't do the transactional data as hierarchy.  not sure the reason behind your requirement.
we can do one of the below :-
1. To have the default view as
| Vendor | Purchasing Organisation | Purchasing Group | Plant | | PO Number| .( keyfigures) | Payment |
and then user can drill down on rest of the characteristics for detailed view later on.
2. or if they don't want to drill down on characteristics;-
we can build 2 reports , one for header level information and then jump to second query for detailed information(item level) using RRI.
first query:
| Vendor | Purchasing Organisation | Purchasing Group | Plant | | PO Number| .( keyfigures) | Payment |
second query:
| Vendor | Purchasing Organisation | Purchasing Group | Plant |  PO Number | Item | Material / Service | Description | .... ( keyfigures) |
Let us know if this works out?

Sakthi.
