Hi,

This is how you can use add attribute method.....

data: lv_info type ref to if_wd_context_info,
        ls_attribute type wdr_context_attribute_info.
 
lv_info = wd_context->get_node_info( )
ls_attribute-name = 'carrid'
ls_attribute-type_name = 's_carr_id'
 
call methods lv_info->add_attribute
exporting
attribute_info = ls_attribute

hi

your answer thanks

but i have any problem .

data: lv_info type ref to IF_WD_CONTEXT_NODE,

ls_attribute type wdr_context_attribute_info.

lv_info = wd_context->get_node_info( ).

ls_attribute-name = 'carrid'.

ls_attribute-type_name = 's_carr_id'.

call method lv_info->add_attribute

exporting

attribute_info = ls_attribute.

firstly ," The result type of the function method cannot be converted into the type of LV_INFO. ."

i do lv_info = wd_context->get_child_node( 'GT_MASTER' ).

and other error,

"add_attribute" method is absent in IF_WD_CONTEXT_NODE . it's F_WD_CONTEXT_NODE_INFO.

Hi,

Please make a change here....

it's not...

data: lv_info type ref to if_wd_context_info,

it is....

data: lv_info type ref to if_wd_context_node_info,

Hi Joshua,

You get the 2 errors due to invalid declaration of your variable lv_info. You have declared it as:

data: lv_info type ref to IF_WD_CONTEXT_NODE

. whereas the correct declaration should be as:

data: lv_info type ref to IF_WD_CONTEXT_NODE_INFO.

hi

CALL METHOD LT_ROOT_INFO->GET_CHILD_NODE

EXPORTING

NAME = 'GT_MASTER'

RECEIVING

CHILD_NODE = lr_flights_info

.

" Define attribute Carrid

ls_attribute-name = 'LGART1'.

ls_attribute-type_name = 'LGART'.

ls_attribute-value_help_mode = '0'.

call method lr_flights_info->add_attribute

exporting attribute_info = ls_attribute.

this is run

thanks Uday Gubbala and Pranav Nagpal

finally

im use this is on alv and i must do change field text

you think how can i do ?

Hi Joshua,

I guess that you want to change the column heading that appears within the ALV. By default the column text shown in the ALV are the S (short) texts from the domain. You can set the M or L text like this:

DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings,
          lr_col_header TYPE REF TO cl_salv_wd_column_header. 

lr_column_settings ?= wd_this->r_table.

" get table of column settings - each line one column 

DATA: lt_columns TYPE salv_wd_t_column_ref.
lt_columns = lr_column_settings->get_columns( ).

DATA: ls_column TYPE salv_wd_s_column_ref.

LOOP AT lt_columns INTO ls_column.
" get header of column 
  lr_col_header = ls_column-r_column->get_header( ).
" change columnheader text to medium text of domain 
  CALL METHOD lr_col_header->set_ddic_binding_field 
                             EXPORTING value = if_salv_wd_c_column_settings=>ddic_bind_medium.
ENLOOP.

Hi Joshua,

If you however intend to set an entirely new text for the column (different from the S/M/L texts maintained at domain level) then you need to delete the DDIC bindings for the column text as well as set the new texts for the column. Try go through the code fragment below which am passing on to you from Thomas Jung's post in [here|;:

data: l_ref_cmp_usage type ref to if_wd_component_usage.
  l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
  if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
  endif.
 
  data l_salv_wd_table type ref to iwci_salv_wd_table.
  l_salv_wd_table = wd_this->wd_cpifc_alv( ).
  data l_table type ref to cl_salv_wd_config_table.
  l_table = l_salv_wd_table->get_model( ).
  data l_column type ref to cl_salv_wd_column.
  data l_header type ref to cl_salv_wd_column_header.
 
 l_column = l_table->if_salv_wd_column_settings~get_column( 'CREATED_BY' ).
  l_header = l_column->get_header( ).
  l_header->set_prop_ddic_binding_field(
    property =  if_salv_wd_c_ddic_binding=>bind_prop_text
    value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
  l_header->set_prop_ddic_binding_field(
    property =  if_salv_wd_c_ddic_binding=>bind_prop_tooltip
    value = if_salv_wd_c_ddic_binding=>ddic_bind_none ).
  l_header->set_tooltip( `TTCreated By` ).
  l_header->set_text( `Created By` ).

Uday Gubbala i will try.

Hi Joshua,

You can define new attributes for the previously created context node by calling the method add_attribute( ) from the reference to the metadata of the node.

ex:

data: lt_root_info type ref to if_wd_context_node_info,
        lr_flights_info type ref to if_wd_context_node_info,
        ls_attribute type wdr_context_attribute_info.

" Get the meta data information of the root context node

lr_root_info = wd_context->get_node_info( ).

" Create node with name FLIGHTS without attributes

lr_flights_info = lr_root_info->add_new_child_node
       exporting name                               = 'FLIGHTS'
                     is_mandatory                    =  abap_false
                     is_multiple                        = abap_true
                     is_mandatory_selection     = abap_false
                     is_multiple_selection         = abap_false
                     is_singleton                      = abap_true
                     is_initialize_lead_selection = abap_true
                     is_static                           = abap_false
      receiving
                    child_node_info                  = lr_flights_info.

" Define attribute Carrid

 ls_attribute-name = 'CARRID'.
 ls_attribute-type_name = 'S_CARR_ID'.
 ls_attribute-value_help_mode = '0'.

 call method lr_flights_info->add_attribute
     exporting attribute_info = ls_attribute.

Creating a context node and its attributes comprises a lot of manually written coding since the method add_attribute( ) has to be called once for each attribute. You can instead use the the method add_new_child_node( ) to even create related attributes by using the static_element_type / static_element_rtti / attribute parameters of this method. Try refer the documentation for more information regarding this.
