Hi,
First get the plant from the screen,
Then according to the palnt you get , do the select statment.
Last using FM: F4IF_INT_TABLE_VALUE_REQUEST.
Do you use dialog program or general program?
If you use dialog program, you can use POV.
process on value-request.
  field p_matnr  module mod_get_F4.
module mod_get_F4.
select matnr from MARC into table it_matnr
where WERKS = P_WERKS .
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
      retfield              = 'MATNR'
     dynpprog               = 'ZTEST'          " program name
     dynpnr                 = '1000'             " screen number
     dynprofield            = 'P_MATNR'
     VALUE_ORG              = 'S'
    tables
      value_tab              = it_matnr
exceptions
   parameter_error        = 1
   no_values_found        = 2
   others                 = 3
if you use general program:
at selection-screen on value-request for p_matnr.
select matnr from MARC into table it_matnr
where WERKS = P_WERKS .
call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
      retfield              = 'MATNR'
     dynpprog               = 'ZTEST_C'          " program name
     dynpnr                 = '1000'             " screen number
     dynprofield            = 'P_MATNR'
     VALUE_ORG              = 'S'
    tables
      value_tab              = it_matnr
exceptions
   parameter_error        = 1
   no_values_found        = 2
   others                 = 3
Hope it helps.
