Problem in getting parameter value from selection screen in web dynpro abap

Hi,

I am facing problem in getting parameter value from selection screen.

Please find my code below:

DATA LT_PAR_ITEM TYPE IF_WD_SELECT_OPTIONS=>TT_SELECTION_SCREEN_ITEM.

FIELD-SYMBOLS:<FS_PAR_ITEM> LIKE LINE OF LT_PAR_ITEM,

<FS_OBJ_USAGE> TYPE REF TO data.

WD_THIS->M_HANDLER->GET_PARAMETER_FIELDS( IMPORTING ET_FIELDS = LT_PAR_ITEM ).

LOOP AT LT_PAR_ITEM ASSIGNING <FS_PAR_ITEM>.

CASE <FS_PAR_ITEM>-M_ID.

WHEN `OBJ_USAGE`.

ASSIGN <FS_PAR_ITEM>-M_VALUE->* TO <FS_OBJ_USAGE>.

[ Here, sy-subrc is 4, <FS_OBJ_USAGE> is not assigning.]

ENDCASE.

ENDLOOP.

So, can any one solve this problem.

Thanks in advance,

Radhika

Hi Radhika,

Try using GET_RANGE_TABLE_OF_SEL_FIELD...

Please Refer below code..

DATA: NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.

DATA: RT_CARRID TYPE REF TO DATA.

DATA: ISFLIGHT TYPE TABLE OF SFLIGHT.

DATA: WSFLIGHT TYPE SFLIGHT.

FIELD-SYMBOLS: <FS_CARRID> TYPE TABLE.

RT_CARRID = WD_THIS->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD( I_ID = 'S_CARR_ID' ).

ASSIGN RT_CARRID->* TO <FS_CARRID>.

CLEAR ISFLIGHT. REFRESH ISFLIGHT.

SELECT * INTO CORRESPONDING FIELDS OF TABLE ISFLIGHT FROM SFLIGHT

WHERE CARRID IN <FS_CARRID>.

NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( NAME = `FLIGHTS` ).

NODE_FLIGHTS->BIND_ELEMENTS( ISFLIGHT ).

Thanks,

Regards,

Kiran
