F4 Help

Former Member — Thu, 29 Sep 2005 05:19:09 GMT

HI ALL,

i have two fields in a screen of a z transaction.

Now i have attached one F4 help to one field (VKORG), and i want to design the F4 help for the second field (VTWEG),in such a way that, if the user select a value for VKORG and go F4 for VTWEG , only the valid value vtweg for that choosen VKORG will be popped up.

The VKORG-VTWEG values are mapped in ZMAP table (userdefined).

Some values=>

VKorg.....................VTWEG

1000.......................10

1000.......................12

1100.......................13

1100.......................14

So my requirement is=>

the user selected vkorg =1000 from F4 help. now when he press F4 in vtweg field, he will get only (10,12) for selection..not all the values. I hope i made the question clear..help me out, reward is guaranteed

Hi,

I am giving the sample code I hope it will help you.

SELECT vkorg vtweg FROM ztable INTO (itab-vkorg, itab-vtweg)

WHERE ..............

APPEND itab.

ENDSELECT.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'vtweg'

dynpprog = w_progname
dynpnr = w_scr_num
dynprofield = 'itab-vtweg'

value_org = 'S'

display = 'F'

stepl = g_stepl

TABLES

value_tab = itab

return_tab = return_values

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.

ELSE .

hide: itab-vkorg.

modify table itab transporting vkorg vtweg.

I hope it will help you.............

Hi,

First of all you need to catch the value entered in

VKORG. You can do it by using FM 'DYNP_VALUES_READ'

that reads the screen parameters.

Since you need to read only one fields value from the screen the code can be written as.

move 'W_VKORG' to t_dynpfield-fieldname.

append t_dynpfield.

Note : Assume 'W_VKORG' is the name of the first field.

call function 'DYNP_VALUES_READ'exporting

dyname = w_dyname

dynumb = w_dynumb

translate_to_upper = 'X'

tables

dynpfields = t_dynpfield

exceptions

invalid_abapworkarea = 01

invalid_dynprofield = 02

invalid_dynproname = 03

invalid_dynpronummer = 04

invalid_request = 05

no_fielddescription = 06

undefind_error = 07.

IF t_dynpfield-FIELDVALUE IS INITIAL.

MESSAGE s032(zi) with 'Enter the VKORG Field.

Then use

LOOP AT ZMAP into wa_ZMAP.

if wa_ZMAP-VKORG = W_VKORG

append wa_VTWEG to t_VTWEG " Intctable for VTWEG

endif.

ENDLOOP.

Note : t_VTWEG is an internal table to hold values for

VTWEG. You need to declare this earlier.

Now you have enough values in t_VTWEG.Pass this to F4 help function mudule.i.e

DATA t_field like DFIES occurs 0.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

DDIC_STRUCTURE = ' '

RETFIELD = 'W_VTWEG

PVALKEY = ' '

DYNPPROG = " Your prog name"

DYNPNR = sy-dynnr

DYNPROFIELD = 'W_VTWEG'

STEPL = 0

WINDOW_TITLE = 'VTWEG'

VALUE = ' '

VALUE_ORG = 'S'

MULTIPLE_CHOICE = ' '
DISPLAY = ' '
CALLBACK_PROGRAM = ' '
CALLBACK_FORM = ' '

TABLES

VALUE_TAB = t_VTWEG

FIELD_TAB = t_field

RETURN_TAB =
DYNPFLD_MAPPING =
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.

Please reward points if this explanation useful.

Thanks,

HI Deepak,

its a module pool program and the field is in screen no 0100, so can just give some hint, where to put the code that you have provided.

Re: F4 Help

Former Member — Thu, 29 Sep 2005 05:59:48 GMT

Please do this.

Note W_VTWEG is the name of the second field in your screen.

Write the following in the Flow logic.

PROCESS ON VALUE-REQUEST.

Field W_VTWEG module get_dir_grp.

Double click on this above stauemen and write the code that I exlained further.

The code that Deepak gave will work unless you press enter or in PAI of any eveny.If you need to direcly press F4 on field 2 after entering the value in Field1 the you need to use FM DYNP_VALUES_READ

Please reward points if this explanation useful.

Regards,

Siva

Hi,

In your screen 100 in PAI.

PROCESS AFTER INPUT.

MODULE USER_COMMAND.

LOOP AT itab.

endloop.

process on value-request.

****After this place that code what ever i gave you earlier.
