F4IF_START_VALUE_REQUEST trouble [+]

Former Member — Thu, 02 Nov 2006 17:46:05 GMT

Hello,

I'm experiencing the following problem using F4IF_START_VALUE_REQUEST function: it returns empty return table. However, all the parameters are filled correctly. Here's the code:



  DATA: lt_returntab TYPE ddshretval OCCURS 0 WITH HEADER LINE ,
        l_shlp TYPE shlp_descr.

  CALL FUNCTION 'F4IF_GET_SHLP_DESCR'
    EXPORTING
      shlpname = 'ZOST_ADVANCED_VBELN'
      shlptype = 'SH'
    IMPORTING
      shlp     = l_shlp.

 
  CALL FUNCTION 'F4IF_START_VALUE_REQUEST'
    EXPORTING
      shlp                = l_shlp
*   DISPONLY            = ' '
*   MAXRECORDS          = 500
*   MULTISEL            = ' '
*   CUCOL               = SY-CUCOL
*   CUROW               = SY-CUROW
* IMPORTING
*   RC                  =
    TABLES
      return_values       = lt_returntab
            .

If I call standalone search-help, it works correctly. What's wrong with the function call or something?

Hi Cyrill,

Code looks extremely fine ...

I understand that RC is optional parameter but just

try uncommenting

<b>Data : RC LIKE Sy-subrc.</b>

<b>* IMPORTING

RC =</b>

and let me know if it works...

Hi Cyrill,

Please check below sample codes from program REXPDSEL.


...
  
call function 'F4IF_GET_SHLP_DESCR'
  exporting
    shlpname  = 'PRPM'
    shlptype  = 'SH'
  importing
    shlp      = g_shlp_descr_t.
                   
loop at g_shlp_descr_t-interface into
        gwa_shlp_descr_t_interface.
  if gwa_shlp_descr_t_interface = 'POSID'.
    gwa_shlp_descr_t_interface-valfield = 'X'.
    modify g_shlp_descr_t-interface from
           gwa_shlp_descr_t_interface.
  endif.
endloop.
                  
call function 'F4IF_START_VALUE_REQUEST'
  exporting
    shlp           = g_shlp_descr_t
    maxrecords     = 500
    multisel       = 'X'
  tables
    return_values  = gt_return_tab.

...

Hope this will help.

Ferry Lianto

Yes. This does solve getting multiple fields' values back from a search help designed to send back multiple fields. Thank you.

In case anybody wants another complete example, here it is:

*Variables for the function that sets screen field values

DATA: dyname LIKE d020s-prog,

dynumb LIKE d020s-dnum.

DATA: BEGIN OF dynpfields OCCURS 3.

INCLUDE STRUCTURE dynpread.

DATA: END OF dynpfields.

DATA: lv_numeric_with_two_bytes TYPE n LENGTH 2.

DATA: lt_returntab TYPE ddshretval OCCURS 0 WITH HEADER LINE ,

l_shlp TYPE shlp_descr,

lv_name_sh TYPE shlpname VALUE 'ZZZZ_SHELP_WITH_TWO_EXPORTS'.

lt_interfaces TYPE ddshifaces,

ls_interfaces TYPE LINE OF ddshifaces.

*( 1 ) - Return all information about the search help

CALL FUNCTION 'F4IF_GET_SHLP_DESCR'

EXPORTING

shlpname = lv_name_sh

shlptype = 'SH'

IMPORTING

shlp = l_shlp.

*( 2 ) - Update to indicate that we want values passed back from more than one field!

lt_interfaces = l_shlp-interface.

ls_interfaces-valfield = yc_charx.

MODIFY lt_interfaces FROM ls_interfaces TRANSPORTING valfield

WHERE shlpfield = 'SBELP' OR shlpfield = 'SBELN'.

*Only proceed to set line number if we got the information!
