hi,

ALV TREE

check these links.

http://www.sapdevelopment.co.uk/reporting/alv/alvtree/alvtree_basic.htm

Check these programs.

e.g

BCALV_TREE_01 ALV tree control: build up the hierarchy tree

BCALV_TREE_02 ALV tree control: event handling

BCALV_TREE_03 ALV tree control: use an own context menu

BCALV_TREE_04 ALV tree control: add a button to the toolbar

BCALV_TREE_05 ALV tree control: add a menu to the toolbar

BCALV_TREE_06 ALV tree control: Icon column and icon for nodes/items

BCALV_TREE_DEMO Demo for ALV tree control

BCALV_TREE_DND ALV tree control: Drag & Drop within a hierarchy tree

BCALV_TREE_DND_MULTIPLE ALV tree control: Drag & Drop within a hierarchy tree

RSDEMO_DRAG_DROP_TREE_MULTI

BCALV_TREE_EVENT_RECEIVER Include BCALV_TREE_EVENT_RECEIVER

BCALV_TREE_EVENT_RECEIVER01

BCALV_TREE_ITEMLAYOUT ALV Tree: Change Item Layouts at Runtime

BCALV_TREE_MOVE_NODE_TEST Demo for ALV tree control

BCALV_TREE_SIMPLE_DEMO Program BCALV_TREE_SIMPLE_DEMO

BCALV_TREE_VERIFY Verifier for ALV Tree and Simple ALV Tree

Also please check the transaction DWDM This will give info also on trees.
