Hi Experts,

Plz let me know how to find out the level count(level number) after expanding the alv tree.

In the UI if i drop down the nodes of a tree till some level, i need to know at what level i am in.

Thanks,

Kumar

hi.

This code will help u..

CALL METHOD G_ALV_TREE->ADD_NODE

EXPORTING

I_RELAT_NODE_KEY = P_RELAT_KEY

IS_NODE_LAYOUT = FOLDER

I_RELATIONSHIP = CL_GUI_COLUMN_TREE=>RELAT_LAST_CHILD

I_NODE_TEXT = L_NODE_TEXT

IS_OUTTAB_LINE = IT_KUNNR

IMPORTING

E_NEW_NODE_KEY = P_L_DATE_KEY.

Hi ,

While you're adding nodes to your tree , you can fill an internal table with two fields which has 2 columns ; NODE KEY and LEVEL.

When a node is picked , you can easily get the node key and find the level using the internal table.

you can just write the level inside the structure of the node . You basiclly add a level field and make it invisible.

Hi Kumar ,

If you've got the node key of the selected node , than you can easily find the level by the help of GET_PARENT

GET_PATH methods of cl_gui_alv_tree. Otherwise , considering the condition that you can't modify the program it is not possible.
