Listbox after selection, no value

Former Member — Tue, 26 Apr 2016 06:30:34 GMT

Hi All,

I am using ABAP Listbox with VRM to set the dropdown.

I am able to set the dropdown, but the user selected value doesnot appear in the parameter specified.

I have tried using VRM_GET_VALUES but the same didnt work.

Please guide.

Below is my code:

REPORT zbw_mosl_file_upd.

TYPE-POOLS: vrm, slis.

TYPES: BEGIN OF ty_retailer,

/bic/zcretalr TYPE /bic/oizcretalr,

END OF ty_retailer.

TYPES: BEGIN OF ty_pzcfilenm2,

checkbox TYPE xfeld,

/bic/zcfilenm TYPE /bic/oizcfilenm,

objvers TYPE rsobjvers,

changed TYPE rsrchangeflag,

/bic/zcstat TYPE /bic/oizcstat,

/bic/zcretalr TYPE /bic/oizcretalr,

END OF ty_pzcfilenm2.

DATA: lt_retailer TYPE TABLE OF ty_retailer,

ls_retailer TYPE ty_retailer.

DATA: lt_pzcfilenm TYPE TABLE OF /bic/pzcfilenm,

ls_pzcfilenm LIKE LINE OF lt_pzcfilenm.

DATA: lt_pzcfilenm2 TYPE TABLE OF ty_pzcfilenm2,

ls_pzcfilenm2 LIKE LINE OF lt_pzcfilenm2.

DATA: lt_fieldcat TYPE slis_t_fieldcat_alv,

ls_fieldcat TYPE slis_fieldcat_alv.

DATA: name TYPE vrm_id,

list TYPE vrm_values,

value LIKE LINE OF list,

lv_records TYPE i,

lv_message TYPE string.

DATA: lv_repid TYPE sy-repid VALUE sy-repid.

DATA lr_grid TYPE REF TO cl_gui_alv_grid.

SELECTION-SCREEN: BEGIN OF BLOCK b1 WITH FRAME TITLE text-001.

PARAMETERS: p_retail LIKE /bic/pzcfilenm-/bic/zcretalr AS LISTBOX VISIBLE LENGTH 30.

SELECTION-SCREEN: END OF BLOCK b1.

AT SELECTION-SCREEN OUTPUT.

SELECT /bic/zcretalr

FROM /bic/pzcfilenm

INTO TABLE lt_retailer

WHERE /bic/zcretalr IS NOT NULL.

IF sy-subrc NE 0.

MESSAGE e000(zbw_mosl_file_upd) WITH 'Error'.

EXIT.

ELSE.

SORT lt_retailer.

DELETE ADJACENT DUPLICATES FROM lt_retailer.

LOOP AT lt_retailer INTO ls_retailer.

value-key = sy-tabix.

value-text = ls_retailer-/bic/zcretalr.

APPEND value TO list.

ENDLOOP.

name = 'P_RETAIL'.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = name

values = list.

ENDIF.

AT SELECTION-SCREEN.

"Fetch all the Filenames which have Loaded status for the selected retailer

* PERFORM fetch_loaded.

CALL FUNCTION 'VRM_GET_VALUES'

EXPORTING

id = name

IMPORTING

values = list.

Hi Shrihari,

By seeing your code, P_RETAIL will have the integer value 0, 1, 2 etc.

The Value of the field in the list box will always be the Key Value.

Thanks and Regards,

Hi Vinay,

I have mapped text value to the dropdown display and key field is filled with integers.

Also P_RETAIL is of the type text which is required to be displayed.

Thanks,

Srihari

Hi,

Please call the code to populate the Listbox in Initialization Event and retrive the value of the selected the value from Selection-Screen field "Listbox" at event "AT Selection-Screen on ".

Thanks

Hi Srihari,

Are you able to see the drop down on the selection screen.

After you select a value from the drop down, in debug mode can you please check what is the value of the field P_RETAIL. Whether P_RETAIL has any value or is it blank.

Hi,

You didn't put 'START-OF-SELECTION' event statement after 'AT SELECTION-SCREEN'. That's why you are not getting the result. Try this and check. It will work.

Remove that function module 'VRM_GET_VALUES'. You will get the value in parameter p_retail directly.

Hi,

You have specified sy-tabix as the key field and defined the parameter P_RETAIL as LISTBOX for /bic/pzcfilenm-/bic/zcretalr which might be the problem.

If you are mentioning sy-tabix as the key of the list, then the parameter has to be defined LIKE sy-tabix AS LISTBOX. With the current ddefinition of the parameter, you have to set ls_retailer-/bic/zcretalr as the key of the list.

Please let me know if this solves your issue.

Regards,

Shayeree.

Hi Srihari,

Use the condense statement after assigning the value to KEY field of your List.

Since you have used SY-TABIX and field VALUE-KEY is of 40 Char.

VALUE-KEY = Sy-tabix.

condense Value-key.

Append value to list.

You should get the value under same Parameter.

Thanks

Hi Srihari,

Once Check your Key Values .

Ex:

w_value-key = 'K1'.

w_value-text = 'SALES'.

append w_value to v_value.

clear w_value.
