Serch Help Exit problem

Hi.

I have this FM created by me.

  ENDIF.

ENDFUNCTION.

My questions is:

Do i have to write something else in some of the STEPS ?

Because i receive the message that the list is empty, but lt_matnr has 397 lines.

I saw that in some further steps, outside my FM, record_tab is refreshed.

There seams to be something missing from my FM, but i can't figure it out.

Can someone help?

Thanks.

Exit Function starts with F4UT

function f4ut_shlp_ext_lgobe.
*"----------------------------------------------------------------------
*"*"Local Interface:
*"  TABLES
*"      SHLP_TAB TYPE  SHLP_DESCT
*"      RECORD_TAB STRUCTURE  SEAHLPRES
*"  CHANGING
*"     VALUE(SHLP) TYPE  SHLP_DESCR
*"     VALUE(CALLCONTROL) LIKE  DDSHF4CTRL STRUCTURE  DDSHF4CTRL

and second when you are using exit function for search help that means using this function we add some extra fields display logic etc.

in the below example i am just showing the search help for LGOBE Text in different language along with other fields so i coded in the DISP step..

if callcontrol-step = 'DISP'.


perform authority_check tables record_tab shlp_tab
                           changing shlp callcontrol.

    exit.
  endif.

form authority_check  tables   record_tab structure seahlpres
                               shlp_tab type shlp_desct
                      changing p_shlp type shlp_descr
                               p_callcontrol type ddshf4ctrl.

data: wa_shlp  type dfies,
        v_lgobe type zt001l-zlgobe_de,
      lt_record type seahlpres occurs 0 with header line.


read table  shlp_tab index 1.
loop at record_tab.
read table shlp_tab-fielddescr into wa_shlp with key tabname = 'T001L'
                                                 fieldname = 'WERKS'.
*if record_tab-string+3(4) = 1000.
  lt_record-string = record_tab-string.
  select single zlgobe_de
         from zt001l
         into v_lgobe
         where werks = record_tab-string+3(4) and
               lgort = record_tab-string+7(4).
 if sy-subrc eq 0.
 lt_record-string+11(16) = v_lgobe.
 clear v_lgobe.
 append lt_record.
 endif.
endloop.

even if you don't do any thing in the exit, but make sure that you have created the Function starts with F4UT*

Hi,

create one sample program and try to use the search help created by you, if you directly execute the function module it will not give desired results.

Thanks,

Sreeram.

Test the search help without the search help exit "z_ricerca_ara_ofi"

confirm whether you are getting 397 or more records?

and also check your selection method (may be view) is correct?

It's too complicated to do it without the exit. I haven't got it yet. 😄

BUT searching by hand in those tables, i get to the same result as the program. So i guess i'm right about those 397 records.

Re: Serch Help Exit problem

Former Member — Tue, 19 Aug 2008 17:05:32 GMT

So it's ok to use record_tab as the result table, right ?

I only need to add something after

if callcontrol-step = 'DISP'.

regarding record_tab (assuming i did the "f4ut*" change)?

Re: Serch Help Exit problem

former_member194669 — Tue, 19 Aug 2008 17:24:38 GMT

What i am suggesting is for testing purpose just remove the function exit and check whether you are getting the records.

another way is to create a database view for that table with filtered records and apply that database view in the "selection method" in the search help.

Hi there guys.

Thanks for the help and for the ideas.

The answer was allot simpler. It was only needed to add one line

callcontrol-step = 'DISP'.

before the corresponding ENDIF of

IF callcontrol-step = 'SELECT'.

It's true that it was not obligatory to do something in that perform (that's why it's still commented), but still I did not have to change the name in F4UT*.

If there is a special reason i have to change it in F4UT* pls tell me.

Thanks again for you help.

The search help exit function will always be identified with F4UT* this is the general convention.

it is documented By SAP in the Search help exit Documentation.
