Screen Help input button

Former Member — Thu, 07 Feb 2008 10:21:16 GMT

Hello people,

I start to work with screen in SAP. I create a screen ( layout, attributes, element list, flow logic) . It work for the moment .

I just want to know how to add a link on the right of my input field to help users. For exemple I have an input with date, and i need a link to calendar or a table... Or a link to a person ID. I need a bouton ( like in standard screen) not just a help with F4 !!!

thanks in advance.

You have to use the event "Process in Help Reguest'.

Ex:


PROCESS BEFORE OUTPUT.
  MODULE INIT.

PROCESS AFTER INPUT.
  MODULE CANCEL AT EXIT-COMMAND.

PROCESS ON VALUE-REQUEST.
  FIELD CARRIER MODULE VALUE_CARRIER.
  FIELD CONNECTION MODULE VALUE_CONNECTION.


REPORT demo_dynpro_f4_help_module .

TYPES: BEGIN OF values,
         carrid TYPE spfli-carrid,
         connid TYPE spfli-connid,
       END OF values.

DATA: carrier(3) TYPE c,
      connection(4) TYPE c.

DATA: progname TYPE sy-repid,
      dynnum   TYPE sy-dynnr,
      dynpro_values TYPE TABLE OF dynpread,
      field_value LIKE LINE OF dynpro_values,
      values_tab TYPE TABLE OF values.

CALL SCREEN 100.

MODULE init OUTPUT.
  progname = sy-repid.
  dynnum   = sy-dynnr.
  CLEAR: field_value, dynpro_values.
  field_value-fieldname = 'CARRIER'.
  APPEND field_value TO dynpro_values.
ENDMODULE.

MODULE cancel INPUT.
  LEAVE PROGRAM.
ENDMODULE.

MODULE value_carrier INPUT.

  CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'
       EXPORTING
            tabname     = 'DEMOF4HELP'
            fieldname   = 'CARRIER1'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'CARRIER'.

ENDMODULE.

MODULE value_connection INPUT.

  CALL FUNCTION 'DYNP_VALUES_READ'
       EXPORTING
            dyname             = progname
            dynumb             = dynnum
            translate_to_upper = 'X'
       TABLES
            dynpfields         = dynpro_values.

  READ TABLE dynpro_values INDEX 1 INTO field_value.

  SELECT  carrid connid
    FROM  spfli
    INTO  CORRESPONDING FIELDS OF TABLE values_tab
    WHERE carrid = field_value-fieldvalue.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
       EXPORTING
            retfield    = 'CONNID'
            dynpprog    = progname
            dynpnr      = dynnum
            dynprofield = 'CONNECTION'
            value_org   = 'S'
       TABLES
            value_tab   = values_tab.

ENDMODULE.

Hi,

Try like this,

First add a push button right side of your text box. and add icon on that push button. ( push button attributes->icon name).

and give function code (push)

Now in PAI event,

when 'push'.

u can do whatever u want such as call other screen or call list, to provide required details.

REWARD POINTS IF HELPFUL,

regards.
