Hi,

If a field in an executable program is defined with reference to an ABAP Dictionary field for which possible entries help is defined, the values from the ABAP Dictionary help are automatically displayed when the user calls the F4 help for that field. To create possible values help for input fields that have no Dictionary reference, or to override the help normally linked to the field, you can create an event block for the event

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

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. It is then up to the programmer to ensure that an appropriate list of values is displayed, and that the user can choose a value from it.

You cannot declare the event block AT SELECTION-SCREEN ON VALUE-REQUEST for input fields on the selection screen that are declared within a logical database. You cannot override the possible values help mechanism of a logical database within the program. You can define separate help within the logical database program using the VALUE-REQUEST option in the PARAMETERS and SELECT-OPTIONS statements.

Ex.

REPORT SELECTION_SCREEN_F4_DEMO.

PARAMETERS: P_CARR_1 TYPE SPFLI-CARRID,

P_CARR_2 TYPE SPFLI-CARRID.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_CARR_2.

CALL SCREEN 100 STARTING AT 10 5

ENDING AT 50 10.

MODULE VALUE_LIST OUTPUT.

SUPPRESS DIALOG.

LEAVE TO LIST-PROCESSING AND RETURN TO SCREEN 0.

SET PF-STATUS SPACE.

NEW-PAGE NO-TITLE.

WRITE 'Star Alliance' COLOR COL_HEADING.

ULINE.

P_CARR_2 = 'AC '.

WRITE: / P_CARR_2 COLOR COL_KEY, 'Air Canada'.

HIDE P_CARR_2.

P_CARR_2 = 'LH '.

WRITE: / P_CARR_2 COLOR COL_KEY, 'Lufthansa'.

HIDE P_CARR_2.

P_CARR_2 = 'SAS'.

WRITE: / P_CARR_2 COLOR COL_KEY, 'SAS'.

HIDE P_CARR_2.

P_CARR_2 = 'THA'.

4 WRITE: / P_CARR_2 COLOR COL_KEY, 'Thai International'.

HIDE P_CARR_2.

P_CARR_2 = 'UA '.

WRITE: / P_CARR_2 COLOR COL_KEY, 'United Airlines'.

HIDE P_CARR_2.

CLEAR P_CARR_2.

ENDMODULE.

AT LINE-SELECTION.

CHECK NOT P_CARR_2 IS INITIAL.

LEAVE TO SCREEN 0.

Bhaskar

hi,

This you can done

If you want to f4 help for FIELD12

write event on that field and also in

the function module that to in the RETFIELD = 'FIELD12'.

at event - At selection-screeen on f4 for field12.

data : begin of itab occurs 0,

field1 type numc,

field2 type char5,

end of itab.

at selection-screen on value-request for werks.

itab-field1 = 0

itab-field2 = c/r

append itab.'

itab-field1 = 1

itab-field2 = c/r

append itab.

itab-field1 = 2

itab-field2 = mail

append itab.

itab-field1 = 3

itab-field2 = ret

append itab.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'FIELD12'

DYNPPROG = sy-cprog

DYNPNR = sy-dynnr

DYNPROFIELD = 'FIELD12'

TABLES

VALUE_TAB = itab.

Hope this will resolve your problem

Either create a search help and attach to the field.

Or use FM 'F4IF_INT_TABLE_VALUE_REQUEST'
