[Former Member]

Hi Gurus,

I am using a internal table, for calling a FM, which require Internal table as its parameter.

e.g. pt_material, its structur is (key, value)

how can i show this Table into a Drop-Down-List, which one is better?

Hi,

You can use DropDownBy key... Please refer to the sample code in WDDOINT method...

method WDDOINIT .
  data:
    Node_Node1 type ref to If_Wd_Context_Node,
    Info_Node1 type ref to IF_WD_CONTEXT_NODE_INFO,
    value_set type TIHTTPNVP,
    wa_value_set TYPE LINE OF TIHTTPNVP.

  Node_Node1 = wd_Context->get_Child_Node( Name = IF_MAIN=>wdctx_Node1 ).

  Info_Node1 = Node_Node1->get_node_info( ).

  wa_value_set-name = `01`.
  wa_value_set-value = `Consultant`.
  APPEND wa_value_set to value_set.
  clear wa_value_set.
  wa_value_set-name = `02`.
  wa_value_set-value = `Senior Consultant`.
  APPEND wa_value_set to value_set.
  clear wa_value_set.
  wa_value_set-name = `03`.
  wa_value_set-value = `Manager Projects`.
  APPEND wa_value_set to value_set.
  clear wa_value_set.

  Info_Node1->set_attribute_value_set( name = 'DESIGNATION'
        value_set = value_set ).


endmethod.

Hope this helps,

Best regards,

Hi Ravikiran,

Thanks for your reply.

Sorry, my problem was, the internal table is dynamic.

structur is Key | name | value

i want to Output parameter pt_material-value in the drop-down, is that possible?

Thanks

Hi,

Loop at your pt_material internal table and build the internal table (Name-Value pair) and pass to the attribute of the node as suggested before...

Hope I am clear..

Hi,

Lets say you have a context attribute 'VALUE' whose values you wish to display as a drop down. After you call the function module and get the data in internal table pt_material, include the following code:

data: lr_node type ref to if_wd_context_node,

lt_valueset type table of wdr_context_attr_value,

ls_valueset type wdr_context_attr_value,

lr_nodeinfo type ref to if_wd_context_node_info,

wa_material type pt_material.

lr_node = wd_context->get_child_node('NODE').

lr_nodeinfo = lr_node->get_node_info( ).

loop at pt_material into wa_material.

ls_valueset-value = wa_material-key.

ls_valueset-text = wa_material-value.

append ls_valueset to lt_valueset.

endloop.

lr_nodeinfo->set_attribute_value_set(

exporting

name = 'VALUE'

valueset = lt_valueset

).

This code is for a drop down by key UI element. In your view, for the dropdownby key element, bind the selectedKey property to 'VALUE' attribute of your context node.

I hope this is what you are looking for.

Hi

Create a node of your internal structure type and bind the values from the internal table to the node using bind_table method of if_wd_context_node.Then bind this node to your dropdown node the UI

Hi Shuo,

Go through the following code.

data:uitab type ref to if_wd_context_node,

roles_map type MYTABLE,

flag type abap_bool.

uitab = wd_Context->get_Child_Node( `DROPDOWN` ).

CALL METHOD UITAB->BIND_TABLE

EXPORTING

NEW_ITEMS = roles_map

SET_INITIAL_ELEMENTS = ABAP_TRUE

.

I am just giving you the an example.here DROPDOWN is a node with the attributes of the table type MYTABLE.And you can get the node instance from the context.

Post if you need some more clarification

Thanks
