[Former Member]

Hello everyone i am new to ABAP could you plz help me

Which <b>call function</b> is to be used for getting F4 help.There are many call functions and which is the best one.Give examples

[Former Member]

F4 help shows you the possible entry help...

For table fields it shows the list of entries from foreign key check or attached search help.

You can assign a F4 help to a field if you want like this.

DATA itab LIKE TABLE OF FILE_TABLE WITH HEADER LINE.

SELECTION-SCREEN BEGIN OF BLOCK b1.

PARAMETERS : fname(128).

SELECTION-SCREEN END OF BLOCK b1.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR fname.

CALL FUNCTION 'TMP_GUI_FILE_OPEN_DIALOG'

• EXPORTING

• WINDOW_TITLE =

• DEFAULT_EXTENSION =

• DEFAULT_FILENAME =

• FILE_FILTER =

• INIT_DIRECTORY =

• MULTISELECTION =

• IMPORTING

• RC =

TABLES

FILE_TABLE = itab

• EXCEPTIONS

• CNTL_ERROR = 1

• OTHERS = 2

.

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

LOOP AT ITAB.

WRITE itab-FILENAME.

ENDLOOP.

I always use the function F4IF_FIELD_VALUE_REQUEST.

example (get a partner from table BUT000 😞

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'

EXPORTING

tabname = 'BUT000'

fieldname = 'PARTNER'

• SEARCHHELP = ' '

• SHLPPARAM = ' '

• DYNPPROG = ' '

• DYNPNR = ' '

• DYNPROFIELD = ' '

• STEPL = 0

• VALUE = ' '

• MULTIPLE_CHOICE = ' '

• DISPLAY = ' '

• SUPPRESS_RECORDLIST = ' '

• CALLBACK_PROGRAM = ' '

• CALLBACK_FORM = ' '

• SELECTION_SCREEN = ' '

• IMPORTING

• USER_RESET =

TABLES

return_tab = return_tab

EXCEPTIONS

field_not_found = 1

no_help_for_field = 2

inconsistent_help = 3

no_values_found = 4

OTHERS = 5

.

IF sy-subrc <> 0.

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

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

ENDIF.

Each FM has its own purpose.

Use this FM to get the file name.

(on presentation server)

call function 'F4_FILENAME'

importing

file_name = p_pcfile.

Hi,

Here is the sample code.Kindly reward points by clicking the star on the left of reply,if it helps.

tables kna1.

data:

begin of t_values occurs 2,

value like kna1-begru,

end of t_values,

t_return like ddshretval occurs 0 with header line.

select-options s_begru for kna1-begru.

at selection-screen on value-request for s_begru-low.

refresh t_values.

t_values = 'PAR*'.

append t_values.

t_values = 'UGG'.

append t_values.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'BEGRU'

value_org = 'S'

tables

value_tab = t_values

return_tab = t_return

exceptions

parameter_error = 1

no_values_found = 2

others = 3.

if sy-subrc = 0.

read table t_return index 1.

s_begru-low = t_return-fieldval.

endif.

Hi ,

The following code will attach custom F4 help to fields.

TYPES : BEGIN of strhelp,

vbeln type vbrk-vbeln,

fkdat type vbrk-fkdat,

end of strhelp.

data : itabhelp type table of strhelp.

data : v_sy_repid type sy-repid,

v_sy_dynnr type sy-dynnr.

load-of-program.

move sy-repid to v_sy_repid.

move sy-dynnr to v_sy_dynnr.

Create a selection screen field say s_vbeln for vbrk-vbeln.

Then write code similar to the following.

At selection-screen on value-request for s_vbeln-low.

select vbeln fkdat from vbrk into table itabhelp.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'VBELN' (this field will be returned when f4 is pressed )

dynprog = v_sy_repid

dynpnr = v_sy_dynnr

dynprofield = 'S_VBELN-LOW'

value_org = 'S'

tables

value_tab = itabhelp

(when F4 is presses values in table itabhelp will be displayed)

Hope this helps you .

hi Rajath,

you can use MATCHCODE OBJECT to get the F4 helps for any field.. it is not mandatory to call a Function..

for example..

  
parameters : p_vbeln like vbak-vbeln MATCHCODE OBJECT vmva.

this will give you the relevant seach help..

Hi,

Use the FM : F4IF_INT_TABLE_VALUE_REQUEST, in F4 selection , if we want to show specific fields , this would be useful for that case.

example :

DATA: BEGIN OF li_anlage OCCURS 0,

anlage TYPE anlage,

sparte TYPE sparte,

vstelle TYPE vstelle,

END OF li_anlage.

DATA: li_ret_tab LIKE ddshretval OCCURS 0 WITH HEADER LINE.

SELECT anlage sparte vstelle

FROM eanl

INTO TABLE li_anlage

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'ANLAGE'

dynpnr = sy-dynnr

dynpprog = sy-repid

dynprofield = 'EANL-ANLAGE'

value_org = 'S'

TABLES

value_tab = li_anlage

return_tab = li_ret_tab

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.

Hello Rajath,

There are many ways to do this.This link gives you list of call functions.

http://www.geocities.com/victorav15/sapr3/abapfun.html

I have recently worked with this and i used

"TMP_GUI_FILE_OPEN_DIALOG" this call function.

DATA W_STRING TYPE STRING.

DATA ITAB LIKE TABLE OF FILE_TABLE WITH HEADER LINE.

PARAMETERS: dataset(132) lower case.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR DATASET.

CALL FUNCTION 'TMP_GUI_FILE_OPEN_DIALOG'

• EXPORTING

• WINDOW_TITLE =

• DEFAULT_EXTENSION =

• DEFAULT_FILENAME =

• FILE_FILTER =

• INIT_DIRECTORY =

• MULTISELECTION =

• IMPORTING

• RC =

TABLES

FILE_TABLE = ITAB

• EXCEPTIONS

• CNTL_ERROR = 1

• OTHERS = 2

.

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 ITAB.

IF SY-SUBRC = 0 .

DATASET = ITAB-FILENAME.

REFRESH ITAB.

CLEAR ITAB.

ENDIF.

IF DATASET IS NOT INITIAL.

W_STRING = DATASET.

ENDIF.

Hope this may help you.
