How to use the tree UIBB (FBI Feeder class)

Hi experts,

Is it possible to use the FPM_TREE_UIBB component to display a BO's nodes and subnodes as a hierarchical list?

I've tried as described below: http://help.sap.com/saphelp_tm90/helpdata/ru/a5/a8171815a6433c8180fb3a95e49def/content.htm?frameset=/ru/39/edbb0ef1644bc4926422da4f6a0b29/frameset.htm&current_toc=/ru/c3/3f78b9e4044bd1b38246f0a7993c42/plain.htm&node_id=34

But, in the MAP_DATA_BO_NODE_TO_UI method of the mapper class, we only receive the entries of the node defined in the tree's FBI view, derived from the wiremodel.  I also tried with adding an associated view to the FBI view, but this only gives the information of one subnode, available as an extra column of the tree rather than a sub layer in the hierarchy.

Does this mean the FBI tree UIBB cannot work with multiple node's, but I have to define a custom 'parent_key' in order to create a hierarchy within the data of one single node of the BO?

Thanks for your advice!

KR,
