Hi,

Use this sample code for getting f1 help.Before that go to se61 create document with the prgm name starts with "Z" as I given here ZHR_HELP and enter the details that you want to display while clicking f1.Here p_data refers check_box which is user defined.

AT SELECTION-SCREEN ON HELP-REQUEST FOR p_data.

CALL FUNCTION 'DSYS_SHOW_FOR_F1HELP'

EXPORTING

application = 'SE61'

dokclass = 'TX'

dokname = 'ZHR_HELP'

viewname = 'STANDARD'

EXCEPTIONS

class_unknown = 0

object_not_found = 0

OTHERS = 0.

Then for F4 use this Function module...

Here p_path and P_FNAME are the name of the input file name.that you have declared.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_path.

CALL FUNCTION 'F4_FILENAME'

EXPORTING

PROGRAM_NAME = SYST-CPROG

DYNPRO_NUMBER = SYST-DYNNR

FIELD_NAME = ' '

IMPORTING

FILE_NAME = P_FNAME.

Hope it will be useful for you.

Thanks,

Sakthi

Hi,

go thru in this..

<b>AT SELECTION SCREEN ON HELP-REQUEST FOR <field></b>

The event is triggered when the user calls the F1 help for the field <field>.

If no corresponding event block has been defined,

Help from the ABAP Dictionary is displayed, or

None at all if the field has no Dictionary reference.

If a corresponding event block exists, it takes precedence over the default help mechanism.

<b>Example </b>

REPORT SELECTION_SCREEN_F1_DEMO.

PARAMETERS: P_CARR_1 TYPE S_CARR_ID,

P_CARR_2 TYPE S_CARR_ID.

AT SELECTION-SCREEN ON HELP-REQUEST FOR P_CARR_2.

CALL SCREEN 100 STARTING AT 10 5 ENDING AT 60 10.

<b>AT SELECTION-SCREEN ON VALUE-REQUEST FOR <field></b>

The event is triggered when the user calls the F4 help for the field <field>.

If no corresponding event block has been defined,

The possible values help from the ABAP Dictionary is displayed, or

None at all if the field has no Dictionary reference.

If a corresponding event block exists, it takes precedence over the default possible values help mechanism.

<b>Example:</b>

data: itab type table of matnr.

parameters: A type matnr.

INITIALIZATION.

SELECT MATNR FROM MARA INTO TABLE ITAB.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR A.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'MATNR'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = ITAB.

<b>AT SELECTION SCREEN ON BLOCK <block></b>

This event is triggered when the contents of all of the fields in a block are passed from the selection screen to the ABAP program.

You can use this event block to check the consistency of the input fields in the block.

If an error message occurs within this event block, the fields in the block are made ready for input again on the selection screen.

<b>example:</b>

REPORT EVENT_DEMO.

SELECTION-SCREEN BEGIN OF BLOCK PART1 WITH FRAME.

PARAMETERS: NUMBER1 TYPE I,

NUMBER2 TYPE I,

NUMBER3 TYPE I.

SELECTION-SCREEN END OF BLOCK PART1.

SELECTION-SCREEN BEGIN OF BLOCK PART2 WITH FRAME.

PARAMETERS: NUMBER4 TYPE I,

NUMBER5 TYPE I,

NUMBER6 TYPE I.

SELECTION-SCREEN END OF BLOCK PART2.

AT SELECTION-SCREEN ON BLOCK PART1.

IF NUMBER3 LT NUMBER2 OR NUMBER3 LT NUMBER1 OR NUMBER2 LT NUMBER1.

MESSAGE E020(HB).

ENDIF.

AT SELECTION-SCREEN ON BLOCK PART2.

IF NUMBER6 LT NUMBER5 OR NUMBER6 LT NUMBER4 OR NUMBER5 LT NUMBER4.

MESSAGE E030(HB).

ENDIF.
