[alex_georgek]

Hi all,

In class CL_GUI_LIST_TREE we have a method called

add_nodes_and_items>.In that method you are exporting

2 tables ie node_table and item_table.I want to know how to populate these 2 tables and also what is the purpose for these 2 tables.

Please explain with a sample code.

Thanks in advance.

Alex.

Hi,

This method is used for Inserting Nodes and Items.

It takes parameters Item_Table and Item_Table_Structure

Where, Item_table is your Internal Table data and Item_Table_Structure which is name of the Structure of the Item in ABAP Dictionary.

CALL METHOD me->ADD_NODES_AND_ITEMS
                   EXPORTING
*                     NODE_TABLE                     =
                     ITEM_TABLE                     = it_tab1
                     ITEM_TABLE_STRUCTURE_NAME      = zitab1
*                   EXCEPTIONS
*                     FAILED                         = 1
*                     CNTL_SYSTEM_ERROR              = 2
*                     ERROR_IN_TABLES                = 3
*                     DP_ERROR                       = 4
*                     TABLE_STRUCTURE_NAME_NOT_FOUND = 5
*                     others                         = 6
                         .
                 IF SY-SUBRC <> 0.
*                  MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*                             WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
             ENDIF.

HTH
