Hi,

I am using RS_TREE_LIST_DISPLAY and passing following parameters.

CALL FUNCTION 'RS_TREE_LIST_DISPLAY'

EXPORTING

callback_program = l_sy-repid

callback_user_command = 'AT_USER_COMMAND'

CALLBACK_TEXT_DISPLAY =
CALLBACK_MOREINFO_DISPLAY =
CALLBACK_COLOR_DISPLAY =
CALLBACK_TOP_OF_PAGE =

callback_gui_status = 'SET_PF_STATUS'

CALLBACK_CONTEXT_MENU =
STATUS = 'IMPLICIT'
CHECK_DUPLICATE_NAME = '1'
COLOR_OF_NODE = '4'
COLOR_OF_MARK = '3'
COLOR_OF_LINK = '1'
COLOR_OF_MATCH = '5'
LOWER_CASE_SENSITIVE = ' '
MODIFICATION_LOG = ' '
NODE_LENGTH = 30
TEXT_LENGTH = 75
TEXT_LENGTH1 = 0
TEXT_LENGTH2 = 0
RETURN_MARKED_SUBTREE = ' '
SCREEN_START_COLUMN = 0
SCREEN_START_LINE = 0
SCREEN_END_COLUMN = 0
SCREEN_END_LINE = 0
SUPPRESS_NODE_OUTPUT = ' '
LAYOUT_MODE = ' '
USE_CONTROL = STREE_USE_LIST

use_control = 'L'

IMPORTING

F15 = F15.

and written USER_COMMAND and SET_PF_STATUS forms also.

But When I click on the + sign on output it gives the error

'Choose the valid one node' something like this.

Pls any one help.

What I have to write in USER_COMMAND to expand the nodes.

hi,

Thanks for the support,

But, what I want is,

when i click on '+' sign of the tree nodes my program is coming out.

As soon as I Click on '+' sign it should expand.

After that If I click on child node some action has to be done.

This is my actual requirement.
