Hi Oswaldo,
Once you enable office integration for report painter, the report output will be shown in Excel and each section of report painter will be shown as a new worksheet.
In order to offer a good user experience in Cost Element analysis by cost center, it makes sense you have the cost center hierarchy at the navigation pane (left) where the user can click over the cost center / cost center group and all information is then displayed.
It's not possible to create new sections dynamically according to selection criteria (for example: one section for each cost center, for excel transform to a new tab).
But in a static way, you can do it, just add several cost center parameter in the selection screen ( zkostl1, zkostl2, zkostl3 ) and create 3 new sections by assigning each corresponding selection parameter. If want to play with that, just copy the report 1VK/1SIP-001 in GRR2.

Glauser
