F4 Help

Former Member — Wed, 02 May 2007 06:30:21 GMT

Hi All,

I have two parameters .

I am providing F4 help for both on at selection screen on value request for field .....

and i am using the function Module 'F4IF_INT_TABLE_VALUE_REQUEST'

and assigning the values through Return_tab of the function Module .

the F4 help for second field is based on first field value.

Now the Problem is if i am selecting the value for first field using the F4 help then i am getting the F4 values for the second field also .

But if i am directly assigning the values for first field without using the F4 help then i am not getting the F4 values for the second field. First field remains blank in debug mode. so i am not getting the F4 values for second field since it is dependent on first field value.

am i missing anything.

I am attaching code of F4 Help for the first field :

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'BUKRS'

dynpprog = sy-repid

dynpnr = sy-dynnr

dynprofield = 'PR_BUKC'

value_org = 'S'

TABLES

value_tab = it_bukrs

return_tab = it_rtab

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

READ TABLE it_rtab INTO wa_rtab INDEX 1.

IF sy-subrc = 0.

pr_bukc = wa_rtab-fieldval.

ENDIF.

Thanks.

Hi,

The problem i can understand is first field remains blank and that is why the second field F4 is not working..

<b>The simple thing you have to do is after entering the value in the first field "press enter" .</b>

Hope this will solve your problem.

Award Points if it solves your purpose.

Hi,

Try this : Make first field obligatory.

Re: F4 Help

Former Member — Wed, 02 May 2007 06:36:37 GMT

You dont have to populate your field by reading return_tab.

Try this :

lv_repid = sy-repid.

lv_dynnr = sy-dynnr.

lv_dyn_field = gc_f4_field.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

ddic_structure = lv_struct

retfield = lv_fieldname

dynpprog = lv_repid

dynpnr = lv_dynnr

dynprofield = 'PR_BUKC'

value_org = gc_value_org

TABLES

value_tab = it_gt_depts

EXCEPTIONS

parameter_error = 1

no_values_found = 2

OTHERS = 3.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

ENDFORM.

And how can both value-request be triggered at same time ?

Only one f4 can come up at one time, unless you are calling two FMs.

Pls explain that

HI Suchi,

F4 help is a PAI event, normally it will be trigerd when any action takes place,

when we press F4, a action takes place and the the AT SELECTIOn-SCREEN ON VALUE REQUEST will be triggerd, if you want to fill the second field also then press enter then it will be filled

Hi Suchi,

You might not writing the "At selection-screen on value request ....." event in sequence of the fields.

For the first field write the its "At selection-screen on value request ....." first, then for the second.

Or can you post your code including the "At selection-screen..." events.

Regards,

Hemant.

Hi Suchi,

In at selection screen on value request for field ( second field )

Use FUNCTION 'DYNP_VALUES_READ' to read the value of the first field

and then based on this value use 'F4IF_INT_TABLE_VALUE_REQUEST' for displaying the F4 values for second field

Sample code to be written on search help of second field

form sub_f4_prctr.

TYPES : BEGIN OF ty_prctr,

prctr TYPE cepct-prctr,

ktext TYPE cepct-ktext,

END OF ty_prctr.

DATA: lt_prctr TYPE TABLE OF ty_prctr,

lt_dynpread TYPE TABLE OF dynpread,

wa_dynpread TYPE dynpread,

lv_line TYPE char01.

gv_progname = sy-repid.

gv_dynnum = sy-dynnr.

Field name of the first field

wa_dynpread-fieldname = 'WA_ZFPASALESGROUP-KOKRS'.

APPEND wa_dynpread TO lt_dynpread.

Function Module to read the screen values

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dyname = gv_progname

dynumb = gv_dynnum

determine_loop_index = lv_line

TABLES

dynpfields = lt_dynpread

EXCEPTIONS

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

OTHERS = 11.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Get the screen value

READ TABLE lt_dynpread INTO wa_dynpread INDEX 1.

IF sy-subrc = 0.

SELECT prctr

ktext

FROM cepct

INTO TABLE lt_prctr

WHERE spras = 'EN'

AND kokrs = wa_dynpread-fieldvalue.

IF sy-subrc = 0.

Call function for F4 search help

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'PRCTR'

dynpprog = gv_progname

dynpnr = gv_dynnum

dynprofield = 'WA_ZFPASALESGROUP-PRCTR'

Hi,

make obligatory for first field & press enter after type a value into 1st field.

Re: F4 Help

Former Member — Wed, 02 May 2007 06:43:33 GMT

Hi suchi,

Before using the F4 help for second field , add this and checkout if it workks

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

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


  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.

Now use F4IF_INT_TABLE_VALUE_REQUEST for the second field F4 help

Dear all,

As some of you have mentioned

First FIeld is a mandatory Field .

and I have tried pressing enter for many number of times.

and my program is not module pool and it is just a normal selection screen program.

Any other suggestions.

Thanks
