Hi Dhiraj.

You can achieve single selection by adding the parameter i_no_intervals = abap_true to the method call:

wd_this->mr_selop->add_selection_field(
                         i_id = lv_fieldname
                         i_no_intervals = abap_true
                         i_no_extension = abap_true
                         i_obligatory = abap_true
                         i_read_only = abap_true
                         it_result = lt_range
                         i_value_help_mode = lv_helpmode ).

Hope this helps.

Hai Dhiraj

You can use dropdown list by using the UI element DropDownByKey.

Define a method to populate the values in the dropdown and call it as follows

the doinit method: <b> wd_this->method_name</b>.

<b><u>And the sample code to paopulte the dropdown by key is as follows:</u></b>:

data:

node_flight type ref to if_wd_context_node,

elem_flight type ref to if_wd_context_element,

stru_flight type if_inputview=>element_flight,

nodeinfo_flight type ref to if_wd_context_node_info,

it_valueset type table of wdr_context_attr_value,

it_scarr type table of scarr,

wa_scarr like line of it_scarr,

wa_valueset like line of it_valueset.

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

node_flight = wd_context->get_child_node( name = if_inputview=>wdctx_flight ).

nodeinfo_flight = node_flight->get_node_info( ).

call method cl_abapwd_flight_model=>get_airlines

receiving

l_scarr = it_scarr

.

loop at it_scarr into wa_scarr.

wa_valueset-value = wa_scarr-carrid.

wa_valueset-text = wa_scarr-url.

append wa_valueset to it_valueset.

endloop.

nodeinfo_flight->set_attribute_value_set(

name = 'CARRID'

value_set = it_valueset ).

Hi Dhiraj.

The method add_selection_fields has the the parameters:

I_AS_DROPDOWN Importing Type WDY_BOOLEAN

IT_VALUE_SET Importing Type WDY_KEY_VALUE_TABLE

Use wdy_key_value_table to set the key - values pairs and set i_as_dropdown to true.

Hi Sasha,

If in ADD_SELECTION_FIELD method the interval is set to no interval that means only single value is passed.So in th case i dont have to create a range table

instead can u suggest in which we shld pass the result and hotto get the value.

Shld i raise another thread for this query

Hi Dhiraj.

You can still pass a range table. The range contains the option EQ instead BT if

you set no intervalls.

If you want to use parameters you have to have SP 12 (I Guess).

Hi Dhiraj.

In addition to what has been said earlier regarding the single element, if your requirement is to add STRICTLY a parameter, see note 1033992.

This feature has been added recently.

Hi Dhiraj.

Looks like you can not use intervalls for dropdown box. The init method of the

select_options component only creates one drop down box per selection field.

But I am still on SP09 and I do not know what is possible in higher SPs.
