Hi narendiran,

1. Its quite simple.

2. Basically there are TWO FMs,

which do the job.

3. just copy paste in new program

and u will know the whole logic.

4.

REPORT abc.

DATA : tr LIKE TABLE OF snodetext WITH HEADER LINE.

*----


data

tr-id = '1'.

tr-tlevel = 1.

tr-name = 'amit'.

APPEND tr.

tr-id = '2'.

tr-tlevel = 2.

tr-name = 'mittal'.

APPEND tr.

*----


display

CALL FUNCTION 'RS_TREE_CONSTRUCT'

TABLES

nodetab = tr

EXCEPTIONS

tree_failure = 1

OTHERS = 4.

CALL FUNCTION 'RS_TREE_LIST_DISPLAY'

.

regards,

amit m.

hi amit

it worked, but i need to implement trees that are interactive i need to click/double click on a node and the nodes under it have to expand.

can you plz help me out?

Hi,

You need to use classes. then you can do things like double/single exapnd etc.

check this demo example <b>SAPTLIST_TREE_CONTROL_DEMO</b>

Hi Naren,

It is better to go in for classes.

One of the classes are CL_SIMPLE_TREE_CONTROL.

Try the transaction code DWDM and you can get some useful programs that will suit your needs.

If you can give me your mail-id I can send you one of my programs on the tree control.

Regards,

Sylendra.

hi

i am trying to implement the tree with interactions like double click in classical list, plz can you tell me wher i can find such examples.

Hi Narendran,

If you see this example <b>SAPTLIST_TREE_CONTROL_DEMO</b>

you can find double click, node expand, interactive tree list. this is an example on interactive tree report.

Check it

Hello Narendiran,

you can implement the node double click or single click (hotspot)

here are the code for the same.


DATA: itab LIKE TABLE OF snodetext WITH KEY id,
wa LIKE snodetext.
wa-type = 'ROOT'. " 1st node of the tree
wa-color = 3. " different attributes
wa-tlevel = 1.
wa-text = 'ROOT'.
wa-tlength = STRLEN( gd_nodes-text ).
APPEND wa TO itab.
CLEAR itab.

wa-type = 'ROOT'. "parent 
wa-color = 3.
wa-tlevel = 2.

wa-text = 'CHILD1'.
wa-kind = 'I'.
wa-tlength = 2 .
wa-tcolor = 0.

APPEND wa TO itab.
CLEAR itab.

* add all the nodes required for the list tree display to this internal table
* constructing the tree by calling the using the function *and using itab internal table
CALL FUNCTION 'RS_TREE_CONSTRUCT'
EXPORTING
insert_id = '000000'
relationship = ' '
TABLES
nodetab = itab
EXCEPTIONS
tree_failure = 1
id_not_found = 2
wrong_relationship = 3
OTHERS = 4.

CALL FUNCTION 'RS_TREE_LIST_DISPLAY'
EXPORTING
callback_program = sy-repid
* callback_user_command = 'USER_COMMAND'
* callback_top_of_page = 'TOP-OF-PAGE'
* callback_gui_status = 'SET_GUI'
* text_length1 = 80
EXCEPTIONS
OTHERS = 1.

* the parameter user_command specifies does the event handling part.

FORM user_command TABLES pt_nodes STRUCTURE seucom
                   USING pv_command TYPE c
                CHANGING pv_exit TYPE c
                         pv_list_refresh TYPE c.

case sy-ucomm.
   WHEN 'TRPI'.
   GET CURSOR FIELD field.
     CASE field.
        WHEN 'NODE'.
           NODE_TEXT= pt_nodes-text1.
* EXECUTE the operation as desired.
    endcase  .
endcase.
endform.

the form statement USER_COMMAND is very important as it has certain parameters and pt_nodes will contain the node_text from 1 to 9 of a particular clicked node.

i hope you find this answer useful.

get back to me if you have any doubts on this.

Hi,

Refer Tcode DWDM.

Try F4 on BCALV*TREE in se38.
