Avoid Enter Hit

Former Member — Tue, 03 Mar 2009 05:39:46 GMT

Hi Everyone,

I had created a selection screen with two parameters.

1st parameter have search help.

I got F4 help on value request for 2nd parameter.

My requirement is, after entering value in 1st parameter, relavant records from table should be fetched

and only those data should be in f4 help for 2nd parameter.

Everything is working fine as per requirement.

Only problem is , after entering data in parameter1, till a ENTER Hit, F4 help for Parameter 2 is not workking.

I think this is for a event trigger, But how can i over come this issue to avoid ENTER HIT.

Thanks in Advance,

Regards

Ravi

the ENTER hit has to be done as the input for the 1st parameter is given only after the sel.screen is displayed..

else we can handle it in the inititalization or some at-selc.scre event..

so only if you put the enter,some action is performed and the coreesponding data is fetched for the 2nd parameter..

Hay try this,(DYNP_VALUES_READ)

aufnr type afpo-aufnr,

end of i_afpo.

data : dyname like d020s-prog value sy-repid,

dynumb like d020s-dnum value '0100'.

data: begin of dynpfields occurs 3.

include structure dynpread.

refresh dynpfields.

move 'PARAMETER 1' to dynpfields-fieldname.

append dynpfields.

Hi Ravi,

Here is a Sample code where for P_EBELN standard search help is working and for P_EBELP, F4 help on value request is done.

Sample code is

REPORT ztest.

PARAMETERS : p_ebeln TYPE ebeln,
             p_ebelp TYPE ebelp.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_ebelp.
  DATA : dynp_fields LIKE dynpread OCCURS 0 WITH HEADER LINE.
  DATA : l_ebeln     TYPE ebeln.
  DATA : BEGIN OF it_ekpo OCCURS 0,
          ebeln TYPE ebeln,
          ebelp TYPE ebelp,
         END OF it_ekpo.

  dynp_fields-fieldname = 'P_EBELN'.
  APPEND dynp_fields TO dynp_fields.

  CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname     = sy-repid
      dynumb     = sy-dynnr
    TABLES
      dynpfields = dynp_fields
    EXCEPTIONS
      OTHERS     = 99.

  READ TABLE dynp_fields WITH KEY fieldname = 'P_EBELN'.
  IF sy-subrc EQ 0.
    IF dynp_fields-fieldvalue IS NOT INITIAL.
      l_ebeln = dynp_fields-fieldvalue.

      SELECT ebeln
             ebelp
        FROM ekpo
        INTO TABLE it_ekpo
       WHERE ebeln = l_ebeln.

      CHECK sy-subrc EQ 0.
      CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
        EXPORTING

Hi,

Use event AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_var2 , and then use like:-


AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_var2.

And refer code for f4 help:-


  TYPES : BEGIN OF it,
            area TYPE yapn-area,
          END OF it.

  DATA : itab TYPE STANDARD TABLE OF it WITH HEADER LINE,
         tb_dynpfields LIKE dynpread OCCURS 0 WITH HEADER LINE,
         spey TYPE yapn-spey.

  CLEAR:   tb_dynpfields.
  REFRESH: tb_dynpfields.

  MOVE 'YAPN-SPEY' TO tb_dynpfields-fieldname.
  APPEND tb_dynpfields.

  CALL FUNCTION 'DYNP_VALUES_READ'

Hi Ravi,

Use the FM giving below:

DYNP_VALUES_UPDATE

Very useful when you want to change a field based on the value entered for another field.

DYNP_VALUES_READ

With luck,

Pritam.
