How to handle help function type in a dynpro

Private_Member_19084 — Mon, 07 Jun 2010 11:00:52 GMT

Hello

I've made a button with the functiontype H ( Help Function) and now I'd like to react on this button.

But in the POV AND POH I can't call a module, because for this I need an input-/outputfield.

(FIELD "FIELDNAME" MODULE "MODULENAME").

My question is, how can I react on this functiontype / "HelpButton" ?

Thx in advance

Christian

What kind of reaction are you expecting on the click of this button. Do you have to display a search help without a screen field?

Regards,

Jayesh

Yes, I would like to show a list of available values BUT without a field.

Therefore I use the function type 'H' on my "help" button.

Or for what is the function type H on a button good for?

Thx in advance

There are two ways:

First************

Process after input.

module user_command.

Code inside module user_command:

IF SY-UCOMM = 'H'      "Function code for help button
*fetch all the list and store into an internal table.

* Call another screen to display the internal table.
endif.

Second*****************

Create an input field on the screen and make it invisible.

Process after input.

module user_command.

Code inside module user_command:

IF SY-UCOMM = 'H'      "Function code for help button
*fetch all the list and store into an internal table.
CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
*         DDIC_STRUCTURE         = ' '
      retfield               = 'name of field of internal table which is to be returned to invisible dynpro field'
*         PVALKEY                = ' '
     dynpprog               = 'program name'
     dynpnr                 = 'dynpro number'
     dynprofield            =  'name of invisible dynpro field'
*    STEPL                  = 0
*    WINDOW_TITLE           =
*    VALUE                  = ' '
    value_org              = 'S'
*   MULTIPLE_CHOICE        = ' '
*   DISPLAY                = ' '
*   CALLBACK_PROGRAM       = ' '
*   CALLBACK_FORM          = ' '
    TABLES
      value_tab              = Internal table containing list to be displayed
*     FIELD_TAB          =
*     RETURN_TAB             =
*      dynpfld_mapping        = 
   EXCEPTIONS
     parameter_error        = 1
     no_values_found        = 2
     OTHERS                 = 3
            .
 
endif.

When I use the function TYPE "H" (not CODE), the PAI does not start.

And for me it is important, that I don't run through the PAI and PBO, so I need the function type H -> only POV or POH!
