Node - Dynamic Attributes

[Former Member]

Hi,

I have a node 'CONF' with attribute ATNAM01. I used a ZSTRUC to create this node. Here my requirement is that based on user inputs I will execute a FM, I will get no of entries in my itab. I need to assign attributes based on itab entries to 'CONF' node dynamically ....

Ex: ATNAM01, ATNAM02....ATNAMNN.

Is it possible? How? Any code/link!

Hi sateesh,

Is your problem statement is some thing like this .Based on data in attribute ATNM01 you need to perform correpsonding treatment .

********************************************************************************************

DATA:

node_check TYPE REF TO if_wd_context_node,

elem_check TYPE REF TO if_wd_context_element,

stru_check TYPE if_start_ior=>element_check ,

item_check_attribute LIKE stru_check-check_attribute.

element = wd_context->get_lead_selection( ).

index = wdevent->get_string( 'INDEX' ).

• navigate from <CONTEXT> to <CHECK> via lead selection

node_check = wd_context->get_child_node( name = if_start_ior=>wdctx_check ).

• get element via lead selection

elem_check = node_check->get_element( ).

• get single attribute

elem_check->get_attribute(

EXPORTING

name = `CHECK_ATTRIBUTE`

IMPORTING

value = item_check_attribute ).

if index EQ 2.

elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_true ).

endif.

if index EQ 1.

elem_check->set_attribute( name = 'CHECK_ATTRIBUTE' value = Abap_false ).

endif.

endmethod.

*********************************************************************************************

Point I want make is based on data populated in attribute <b>check_attribute</b>

.I have identified index of attribute and accordingly performed treatment.

Hope this will help you .

If yes give points.

Cheers!

Hello Sateesh.

Have a look at the class <b>cl_wd_dynamic_tool</b>. You can use methods of this

class to dynamically at nodes to your context.

lr_rootnode_info   type ref to if_wd_context_node_info

lr_rootnode_info = wd_context->get_node_info( ).

    cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
      parent_info = lr_rootnode_info
      node_name = 'NAME'
      structure_name = 'ZSTRUCT'
      is_multiple = abap_true ).

Hope this helps.

Hi.

Get the node info of the dynamically created node.

Then call method SET_ATTRIBUTE_VALUE_HELP of node info to set the

value help.

Hi Jagruti.

You have to define the component usage at the properties level of your view.
