Disable multiple selection in search help

[marcus_hoepfner]

Hello,

I have a search help with a function call inside. I am just using a search help to get all the logic so that I do not need to implement a dynpro popup.

I am getting up to five different values now in the selopt-table. Since fm can not handle multiple values I have the following coding:

IF callcontrol-step = 'SELECT'.
    LOOP AT shlp-selopt INTO ls_shlp_selopt
        WHERE ( shlpfield = 'COUNTRY'
           OR shlpfield = 'STATE'
           OR shlpfield = 'ZIPCODE'
           OR shlpfield = 'CITY'
           OR shlpfield = 'COUNTY' )
          AND ( sign <> 'I'
           OR option <> 'EQ' ).
      callcontrol-step = 'PRESEL'.
      MESSAGE i651(56) DISPLAY LIKE 'E'.
      EXIT.
    ENDLOOP.
  ENDIF.

That works fine but may confuse the user (because first he can enter multiple values and afterwards they are forbidden. Is it possbile to remove the multiple selection button from the sh? Maybe in the PRESEL step?!

Thanks for you help,

Marcus

Hello Marcus

The following sample report ZUS_SDN_CALL_SEARCHHELP shows how to switch between single and multiple selection for a search help.

END-OF-SELECTION.

Now if you look under the hood of the second function module you see how the switch is done internally:

  CALLCONTROL-MULTISEL = MULTISEL.  " switch single/multiple selection

Hi Uwe,

that did not directly help. Because I already have a search help exit and don't know how to use a report there.

But with the help of you comment I found the parameter callcontrol-multisel. Unfortunately setting this to space did not help. But a where used list showed me this example:

CALL FUNCTION 'F4UT_SUPPRESS_SELECT_OPTIONS'
        EXPORTING
          parameter         = 'my_fieldname'
        TABLES
          shlp_tab          = shlp_tab
          record_tab        = record_tab
        CHANGING
          shlp              = shlp
          callcontrol       = callcontrol
        EXCEPTIONS
          parameter_unknown = 1
          OTHERS            = 2.

... and that helped me in the presel step.

Strange.. but this does not working in WD-ABAP. But that I'll clarify with the WD-guys.

Thank you for showing me the right path, even if this was not your motivation.
