Make your own search help (selecting only non-blocked vendors) and include this in the collective search help KRED.

Well define your own F4 help

by using the event

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

And under this event u can use one of the Function modules

HELP_VALUES_GET_WITH_TABLE

Show a list of possible values for F4 popup help on selection screens. This function module pops up a screen that is just like all the other F4

helps, so it looks like the rest of the SAP system. Very useful for providing dropdowns on fields that do not have them predefined.

Example

DATA: lc_werks LIKE t001w-werks,

ltab_fields LIKE help_value OCCURS 0 with header line,

BEGIN OF ltab_values OCCURS 0,

feld(40) TYPE c,

END OF ltab_values.

*-- Set up fields to retrieve data

ltab_fields-tabname = 'T001W'.

ltab_fields-fieldname = 'WERKS'.

ltab_fields-selectflag = 'X'.

APPEND ltab_fields.

ltab_fields-tabname = 'T001W'.

ltab_fields-fieldname = 'NAME1'.

ltab_fields-selectflag = space.

APPEND ltab_fields.

*-- Fill values

select * from t001w.

ltab_values-feld = t001w-werks.

append ltab_values.

ltab_values-feld = t001w-name1.

append ltab_values.

endselect.

CALL FUNCTION 'HELP_VALUES_GET_WITH_TABLE'

EXPORTING

fieldname = 'WERKS'

tabname = 'T001W'

title_in_values_list = 'Select a value'

IMPORTING

select_value = lc_werks

TABLES

fields = ltab_fields

valuetab = ltab_values

EXCEPTIONS

field_not_in_ddic = 01

more_then_one_selectfield = 02

no_selectfield = 03.
