Display Cost center (group) hierarchy in a ALV tree display

Does anyone know if there is FM or BAPI that can take the cost center group hierarchy (I used the <b>G_SET_TREE_IMPORT</b> to get the cost center hierarchy) and display in an ALV tree display? Need to customize a report painter report which displays a nice ALV tree list of cost center hierarchy at the left and posting details in each cost elements at the right when each node is doubled clicked.

I think I need to create two containers, one display the hierarchy tree, and one displays the posting. However, I cannot get the whole cost center hierarchy displayed with the parent-child node look. I have tried the logic in <b>BCALV_TREE_DEMO</b>. Does not quite fit the requirements.

Anyone has any advice or sample, please share with me.

Thank you,
