If it's in a report, you could use the sentence AT SELECTION SCREEN ON VALUE REQUEST.

Hi Indu,

For providing the Help value for a particular field you need to provide for this field a check table.

Reward points if helpful.

F4IF_INT_TABLE_VALUE_REQUEST

This function module displays a value list that you created in an ABAP program. The value list is passed to the function module as the table parameter VALUE_TAB. If you specify the import parameters DYNPPROG, DYNPNR, and DYNPROFIELD, the user’s selection is returned to the corresponding field on the screen. If you specify the table parameter RETURN_TAB, the selection is returned into the table instead.

FM DYNP_VALUES_READ can read the values of screen fields

Have a look at below sample code:

REPORT ZTEST_F4 .

DATA : BEGIN OF ITAB OCCURS 0,

NAME LIKE KNVK-NAMEV,

E_MAIL LIKE ADR6-SMTP_ADDR,

END OF ITAB.

PARAMETER : P_EMAIL LIKE ADR6-SMTP_ADDR.

INITIALIZATION.

ITAB-NAME = 'A'.

ITAB-E_MAIL = email@removed '.

APPEND ITAB.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_EMAIL.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'E_MAIL'

DYNPPROG = 'ZTEST_F4'

DYNPNR = '1000'

DYNPROFIELD = 'P_EMAIL'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = ITAB

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3

Another Code sample:

REPORT DEMO_DYNPRO_F4_HELP_MODULE.

TYPES: BEGIN OF VALUES,

CARRID TYPE SPFLI-CARRID,

CONNID TYPE SPFLI-CONNID,

END OF VALUES.

DATA: CARRIER(3) TYPE C,

CONNECTION(4) TYPE C.

DATA: PROGNAME LIKE SY-REPID,

DYNNUM LIKE SY-DYNNR,

DYNPRO_VALUES TYPE TABLE OF DYNPREAD,

FIELD_VALUE LIKE LINE OF DYNPRO_VALUES,

VALUES_TAB TYPE TABLE OF VALUES.

CALL SCREEN 100.

MODULE INIT OUTPUT.

PROGNAME = SY-REPID.

DYNNUM = SY-DYNNR.

CLEAR: FIELD_VALUE, DYNPRO_VALUES.

FIELD_VALUE-FIELDNAME = 'CARRIER'.

APPEND FIELD_VALUE TO DYNPRO_VALUES.

ENDMODULE.

MODULE CANCEL INPUT.

LEAVE PROGRAM.

ENDMODULE.

MODULE VALUE_CONNECTION INPUT.

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.

SELECT CARRID CONNID

FROM SPFLI

INTO CORRESPONDING FIELDS OF TABLE VALUES_TAB

WHERE CARRID = FIELD_VALUE-FIELDVALUE.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'CONNID'

DYNPPROG = PROGNAME

DYNPNR = DYNNUM

DYNPROFIELD = 'CONNECTION'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = VALUES_TAB.

ENDMODULE.

The screen flow logic is as follows:

PROCESS BEFORE OUTPUT.

MODULE INIT.

PROCESS AFTER INPUT.

MODULE CANCEL AT EXIT-COMMAND.

PROCESS ON VALUE-REQUEST.

FIELD CONNECTION MODULE VALUE_CONNECTION.

For the Flight number field, the POV module VALUE_CONNECTION is called. The

function module DYNP_VALUE_READ transports the value of the screen field CARRIER into the program. The program then reads the corresponding values from the database table SPFLI into the internal table VALUES_TAB using a SELECT statement, and passes the internal table to F4IF_INT_TABLE_VALUE_REQUEST. This displays the internal table as input help, and places the user’s selection into the screen field CONNECTION.

I hope it helps.

hi chk this sample code:

       END OF T_VALTAB.

Hi,

Check the below code.

parameters: p_name like p0001-ename.

data: begin of it_name occurs 0,

name like p0001-ename,

end of it_name.

data: v_num type i.

at selection-screen on value-request for p_name.

if v_num is initial.

it_name-name = 'India'.

append it_name.

it_name-name = 'China'.

append it_name.

it_name-name = 'Japan'.

append it_name.

it_name-name = 'Indonesia'.

append it_name.

v_num = v_num + 1.

endif.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'NAME'

DYNPPROG = SY-CPROG

DYNPNR = SY-DYNNR
