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,

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>

PARAMETERS: P_CARR_1 TYPE S_CARR_ID,

P_CARR_2 TYPE S_CARR_ID.

<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

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.
