unable to retreive values from selection screen built using WDR_SELEC_OPTIO

[Former Member]

Hi All,

I have created a selection screen as below

lr_field = wd_this->m_handler->create_range_table( 'YFMTFLOW' ).
*  ASSIGN lr_field->* TO <fs_range>.
*  ls_date-sign   = 'I'.
*  ls_date-option = 'EQ'.
*  ls_date-low    = 'US'.
*  APPEND ls_date TO <fs_range>.
* Add the select-option to the group
  wd_this->m_handler->add_selection_field(
    i_id           = 'FLOW'
    i_within_block = 'PROC'
    i_no_intervals = abap_true
    it_result      = lr_field ).

If i enter some value and click a button to retireve the values as below

DATA
    lt_sel_item TYPE if_wd_select_options=>tt_selection_screen_item.

types: ty_flow type range of yfmtflow.
  FIELD-SYMBOLS:
    <fs_sel_item> LIKE LINE OF lt_sel_item,
    <fs_process>   TYPE yfmtprocess,
    <fs_flow>   TYPE ty_flow.



* Get the selection-screen items
  l_handler->get_selection_screen_items(
    IMPORTING et_selection_screen_items = lt_sel_item ).

* Retrieve the values from the select-options items
  LOOP AT lt_sel_item ASSIGNING <fs_sel_item>.
    CASE <fs_sel_item>-m_id.
      WHEN `PROCESS`.
        ASSIGN <fs_sel_item>-m_value->* TO <fs_process>.
      WHEN 'FLOW'.
        ASSIGN <fs_sel_item>-mt_range_table->* TO <fs_flow>.
    ENDCASE.
  ENDLOOP.

<fs_flow> is empty

but after I enter value and then press enter and then click the button to retrieve the values I am able to get low value <fs_flow> not the sign and option

Is it the standard functionality ,if yes how can we overcome

Thanks

Hi All,

I am unable to read the values from selection screen, earlier I used to retrieve all selection fields into RANGE_TABLE using method GET_SELECTION_SCREEN_ITEMS, but now it is not working.

So my question is that do I need call the following statement for each selection field as below ? what about if  selection screen contains many fields, is there any other method which retrieves all at one go?

CALL METHOD wd_this->m_handler->get_range_table_of_sel_field

   EXPORTING

     i_id           = 'BUKRS'

   receiving

     rt_range_table = rt_range_table.

ASSIGN rt_range_table->* to <fs_bukrs>.

I remember the following method which used to retrieve all selection fields into RANGE_TABLE

CALL METHOD wd_this->m_handler->get_selection_screen_items

     IMPORTING

       et_selection_screen_items = lt_screen_items.

LOOP AT lt_screen_items ASSIGNING <fs_items>.

     CASE <fs_items>-m_id.

       WHEN 'BUKRS'.

         ASSIGN <fs_items>-mt_range_table->* TO <fs_bukrs>.

But unfortunately it is not working now, I don't understand what could be the reason, please help

Hello,

It's not possible. It will work as expected.

Once you got the lt_screen_items(type get_selection_screen_items), instead of making the loop try to read the index, as your are going to read only BUKRS.

And then assign the range table.

ASSIGN <fs_items>-mt_range_table->* TO <fs_bukrs>(Type wd_this->elements_range).

BR,

RAM.

HI Murugan,

Thanks for your reply.

Actually I have many screen items, I just shown only one item 'BUKRS' of LOOP statement.

Method 'get_selection_screen_items' is not working, interestingly the following code is working fine

CALL METHOD wd_this->m_handler->get_range_table_of_sel_field

   EXPORTING

     i_id           = 'BUKRS'

   receiving

     rt_range_table = rt_range_table.

ASSIGN rt_range_table->* to <fs_bukrs>.

BR

Hi,

Try  the below code.Here i've created selection option field namely AGR_NAME.

DATA rt_agr_name              TYPE REF TO data.+

* Retrieve the data from the select option
    rt_agr_name = lv_r_helper_class->get_range_table_of_sel_field( i_id = 'AGR_NAME' ).

* Assign it to a field symbol
    ASSIGN rt_agr_name->* TO <fs_agr_name>.

Thanks
