Simple Tree Problem

Former Member — Thu, 19 Apr 2007 16:31:38 GMT

Hi all.

I read the table 'dd03l' to get all fields of one Table.

The result are 63 Fields.

The select:

  SELECT fieldname FROM dd03l INTO ls_fields-fieldname
      WHERE tabname  = gf_database
        AND as4local = 'A'
        AND as4vers  = 0
        AND position < 59
        AND datatype <> 'CLNT'.
    APPEND ls_fields TO lt_fields.
  ENDSELECT.

Ok, now i want to make a simple Tree with this fieldnames, like this:

Tablename
 - Field1
 - Field2
 - Field3

and so on...

No Problem?But i get a Dump, when i dont set this Argument ' AND position < 59'.

When i write position < 60, the result is a Dump. When i omit this Argument, i get a Dump. Because the Table, which i want to get all fields, have more then 59 Fields.

Why???

Here my Tree Coding:


  node-node_key = 'Root'.                                   
  CLEAR node-relatkey.      
  CLEAR node-relatship. 
  node-hidden = ' '.    
  node-disabled = ' '. 
  node-isfolder = 'X'.    
  CLEAR node-n_image.   
  CLEAR node-exp_image.
  CLEAR node-expander.  
  node-text = gf_database.
  APPEND node TO node_table.

  CLEAR gf_zaehler.
  CLEAR lf_fullzaehl.


  LOOP AT lt_fields INTO ls_fields.

    IF gf_zaehler EQ 10 OR gf_zaehler EQ 0.
      lf_fullzaehl = lf_fullzaehl + gf_zaehler.
      lf_zahltxt = lf_fullzaehl.
      CONCATENATE 'von' lf_zahltxt
             INTO lf_nodekeytxt
        SEPARATED BY space.

      CLEAR node.
      node-node_key = lf_nodekeytxt.                        
      node-relatkey = 'Root'.
      node-relatship = cl_gui_list_tree=>relat_last_child.
      node-isfolder = 'X'.
      node-text = lf_nodekeytxt.
      APPEND node TO node_table.

      CLEAR gf_zaehler.
    ENDIF.


    CLEAR node.
    node-node_key = ls_fields-fieldname.                    
    node-relatkey = lf_nodekeytxt.
    node-relatship = cl_gui_simple_tree=>relat_last_child.
    node-hidden = ' '.
    node-disabled = ' '.
    node-isfolder = ' '.
    CLEAR node-n_image.
    CLEAR node-exp_image.
    node-expander = ' '.
    node-text = ls_fields-fieldname.
    APPEND node TO node_table.

    gf_zaehler = gf_zaehler + 1.

  ENDLOOP.

  CALL METHOD g_tree->add_nodes
    EXPORTING
      table_structure_name           = 'MTREESNODE'
      node_table                     = node_table
    EXCEPTIONS
      failed                         = 1
      error_in_node_table            = 2
      dp_error                       = 3
      table_structure_name_not_found = 4
      OTHERS                         = 5.
  IF sy-subrc <> 0.
    MESSAGE a999.
  ENDIF.

What can i do???

Thx 4 help.

Sincerely yours

Hello Markus

I understand neither the reason for the dump nor your SELECT statement. If you want to read metadata of tables then you should use function module <b>DDIF_FIELDINFO_GET</b> (set IMPORTING parameter ALL_TYPES = 'X').

Alternatively, you could use function module <b>LVC_FIELDCATALOG_MERGE</b>. By default this function module does not return the client field (I_CLIENT_NEVER_DISPLAY = 'X').

Hello Uwe,

maybe its not the finest way, but the SELECT statement works fine. I get all fieldnames.

I have a second Report, a little bit different from the one i spoken in my first posting. There i get the Tree with all Fields, and i used the same SELECT statement. But the tree dosent looks fine, because all 'fieldnames' are root childs....

i can post it tomorrow. but i mean the select is not the problem.

I found one mistake in the second coding.

*-- Nun die Felder anhängen und dem jeweiligen Verzeichnis zuordnen
    CLEAR node.
*    ADD 1 TO nodekey.
    node-node_key   = lf_feldname.
    node-relatkey   = lf_nodekeytxt.
    node-relatship  = cl_gui_list_tree=>relat_last_child.
    node-dragdropid = handle_drag.
    node-hidden     = ' '.
    node-disabled   = ' '.
    node-isfolder   = ' '.
    APPEND node TO node_table.

Wrong relatkey.

And i found the point, when the Dump activated.

At the moment when the Method "cl_gui_cfw=>flush" is triggered.

Can anyone help?

Thanks.
