Problem with Field symbol in WD action

[former_member210563]

Hi,

I have been debugging the code pasted here, but it keeps returning "Field symbol <FS_PSPNR> is not yet assigned".

If I run my app, I get an Error 500 RABAX_STATE.

Perhaps someone here can see what is wrong here.

METHOD onactiongetdata .

   TYPES:

   lty_r_pspnr TYPE RANGE OF ps_posnr,

   tty_empwbs type STANDARD TABLE OF zhr_empwbs.



  DATA

    lr_empwbs    TYPE REF TO if_wd_context_node.



* Variables used to retrieve the values of select-options fields

  DATA

    lt_sel_item TYPE if_wd_select_options=>tt_selection_screen_item.



  FIELD-SYMBOLS:

    <fs_sel_item> LIKE LINE OF lt_sel_item,

    <fs_pspnr>   TYPE ps_posnr.



* Get the selection-screen items

  wd_this->m_helper->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 `PSPNR`.                                    "WBS Number

        ASSIGN <fs_sel_item>-m_value->* TO <fs_pspnr>.

    ENDCASE.

  ENDLOOP.



* Retrieve the data from the database table



  SELECT pernr pspnr sdatum edatum

    FROM zhr_empwbs

    INTO CORRESPONDING FIELDS OF TABLE wd_this->empwbs

    WHERE pspnr = <fs_pspnr>.



* Filter the data for responsible

* Check that project is active

*



* Bind the data to the context



  lr_empwbs = wd_context->get_child_node( name = `EMPWBS` ).

  lr_empwbs->bind_table( wd_this->empwbs ).



ENDMETHOD.

Hi,

You need to see, whether lt_sel_item contains PSPNR without initial values.

Also it is advisable to write,

if <fs_pspnr> is bound.

  SELECT pernr pspnr sdatum edatum

    FROM zhr_empwbs

    INTO CORRESPONDING FIELDS OF TABLE wd_this->empwbs

    WHERE pspnr = <fs_pspnr>.

endif.

Hope this helps u.,

Hi,

Thanks for your reply. I went debugging Again and found out that if I hit Enter after parameter

search field was filled. Then it worked.and lt_sel_item contained the value from the parameter field.

Is there any way to avoid pressing Enter after entering a value in the parameter field ?

Hi,

I guess you are using select options! . If so refer this document : http://scn.sap.com/community/web-dynpro-abap/blog/2005/12/20/using-select-options-in-a-web-dynproaba...

This will help u.

Hi,

No it is actually a parameter field. But thanks Again.
