1) to validate a screen field u have to write code in PAi as follows -

PROCESS AFTER INPUT.

field itab-pernr MODULE CHECK_PERNR. "itab-pernr is screen field

module CHECK_PERNR input.

IF ( ( ITAB-PERNR EQ SPACE ) and ( itab-pernr co '0123456789' ) ).

MESSAGE E000(000) WITH 'MANDATORY FIELD'.

ENDIF.

endmodule.

2) to add F4 help on a screen field ,u have to use event "value-request" as follows -

PROCESS ON VALUE-REQUEST.

FIELD ITAB-PERNR MODULE F4_HELP.

module F4_HELP input.

data: begin of lt_all occurs 0.

include structure DYNPREAD.

data end of lt_all.

data: begin of lt_selected occurs 0.

include structure DDSHRETVAL.

data: end of lt_selected.

DATA: BEGIN OF lt_code OCCURS 0,

code LIKE zgill_main-PERNR,

END OF lt_code.

data no_dyn like sy-dynnr.

no_dyn = sy-dynnr. "give the scren no directly or sy-dynnr in case of report.

*At selection-screen on value-request for ECODE.

select PERNR into table lt_code from zgill_main.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'ITAB-PERNR'

dynpprog = sy-repid

dynpnr = no_dyn

dynprofield = 'ITAB-PERNR'

window_title = 'Employee Details'

value_org = 'S'

DISPLAY = 'F'

TABLES

value_tab = lt_code

RETURN_TAB = lt_selected.

EXCEPTIONS
PARAMETER_ERROR = 1
NO_VALUES_FOUND = 2
OTHERS = 3

*if sy-subrc eq '0' .

write: 'success'.

*endif.

read table lt_selected index sy-tabix.

move lt_selected-fieldval to ITAB-PERNR.

endmodule. " F4_HELP INPUT

reward points if helpfull

Mahesh,

There is an event called Process on Value Request, which satisfied ur f4 functionality.

U should code:

Process on value request.

field table-fieldname module val.

double click on val.

u can write the code as per ur requirement in module pool pgm.

u can use function modules - 'popup_with_table_display' or 'f4if_int_table valuerequest'. u have to pass the fieldname that needs that f4 functionality in the fm.

Regards...

Arun.

declare internal table of type DDSHRETVAL

data:TP_DIRTY LIKE DDSHRETVAL OCCURS 0 WITH HEADER LINE.

MODULE F4HELP INPUT.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'NAME'

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNNR

DYNPROFIELD = 'NAME1'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = ITAB

RETURN_TAB = TP_DIRTY.

ENDMODULE. " F4HELP INPUT

note : NAME is the field of table itab, the value of which is used as a dropdown when f4 is clicked on screen field NAME1.

just fetch data at PBO event as per ur requiremnt -

PROCESS BEFORE OUTPUT.

MODULE CHECK_RECORD.

module CHECK_RECORD output.

SELECT SINGLE * FROM ZGILL_MAIN

WHERE PERNR = ITAB-PERNR.

ITAB-PERNR = ZGILL_MAIN-PERNR. "itab-pernr is my field name on screen

ITAB-NAME = ZGILL_MAIN-NAME.

ITAB-DOB = ZGILL_MAIN-DOB.

ITAB-ORG = ZGILL_MAIN-ORG.

endmodule. " CHECK_RECORD OUTPUT

u can check ur screen field names and fetch data in them..

Suppose u have added ZFIELD to the standard program screen. If u want to display values from any standard SAP table then assign search help to ZFIELD using SE11 transaction . If u want to display values which are not from standard table then define one internal table e.g. ITAB populate this internal table and use following function module in PROCESS ON VALUE-REQUEST event.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = l_retfield "returning field

dynpprog = l_program "Program name

dynpnr = l_sydynnr "Screen number

dynprofield = l_dynprofield "Screen field

value_org = c_s "Sturctured

TABLES

value_tab = i_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.

As far as validation is concerned if the value is standard SAP table value , validate using select command and if it is not standard SAP table value validate using READ command on ITAB table populated above....
