Se requiere imprementar el metodo AT_F4 de la BADI WBS_USER_FIELDS_F4.
Para hacerlo deberas de entrar en la transaccion SE19 y crear la implementacion ZWBS_USER_FIELDS_F4.
Una vez que que la hayas creado deberas de implementar el metodo AT_F4. Aqui dejo el ejemplo de codigo que encontre navegando en la red


types returntab type table of ddshretval initial size 0.

data : tabname type dfies-tabname,

fieldname type dfies-fieldname,

searchhelp type shlpname.

data: return_tab type returntab.
data : valuestab type ddshretval.

case i_user_field.
when 'PRPS-USR00'.
tabname = 'ZIM_ORGANISMOS'.
fieldname = 'ZIDORG'.
searchhelp = 'ZIM_ORGANISMOS'.
* WHEN 'PRPS-USR01'.
* tabname = 'ZAMC_SUBGROUPS'.
* fieldname = 'ZSGROUP'.
* searchhelp = 'ZAMC_SUBGROUPS '.
endcase.

if not tabname is initial.
call function 'F4_FIELD_ON_VALUE_REQUEST'

exporting

tabname = tabname

fieldname = fieldname

searchhelp = searchhelp

* DYNPPROG = ' '
* DYNPNR = ' '

endif.
loop at return_tab into valuestab.
