HI,

consider this example it will solve ur problem:

If the requirement in selection screen is:

There are 2parameters in selection screen. For e.g. matnr and werks.

If I am giving matnr then respect to that matnr i should get only those plant in F4 help.

Solution:

AT SELECTION-SCREEN ON VALUE-REQUEST FOR werks.

select the werks based on plant in internal.table 
use f.m

F4IF_INT_TABLE_VALUE_REQUEST.
and pass the i.tab here in 

tables
value_t = i.tab

Follow the psudo code below.

Note: it_matnr has only single field MATNR.

**--- Return table to handle selected field in F4 help ---**

data: it_return like ddshretval occurs 0 with header line.
 
parameters: p_matnr type marc-matnr,
                  p_werks type marc-werks.
 
at selection-screen on value-request for p_repnam.
 
  select matnr
         from marc
         into table it_matnr
         where werks eq p_werks.
 
  call function 'F4IF_INT_TABLE_VALUE_REQUEST'
    exporting
      retfield         = 'OBJ_NAME'
      dynpprog         = sy-cprog
      dynpnr           = sy-dynnr
      value_org        = 'S'
      callback_program = sy-cprog
    tables
      value_tab        = it_matnr
      return_tab       = it_return
    exceptions
      parameter_error  = 1
      no_values_found  = 2.
 
  if sy-subrc eq 0.
    loop at it_return.
      clear p_repnam.
      p_repnam = it_return-fieldval.
    endloop.
 
  endif.

Hi,

Yes we can read without event.

Declare the variables referring to foreign key table or referenced tables:

Example:

Parameters:

P_carrid type sflight-carrid,

p_connid type sflight-connid.

Her spfli is the parent table but SFlight is forign key table.

So here what ever value you give in Carrid and press f4 on connid

value will appear based on carrid.

Hope this resolves your issue.

Gurpreet

Hi ...

Use the Functio module 'DYNP_VALUES_READ to get the value of the section screen parameter.

Get the selection screen value dynamically

call function 'DYNP_VALUES_READ'

exporting

dyname = sy-repid " Program name

dynumb = sy-dynnr " Screen number

tables

dynpfields = l_i_dynp

exceptions

invalid_abapworkarea = 1

invalid_dynprofield = 2

invalid_dynproname = 3

invalid_dynpronummer = 4

invalid_request = 5

no_fielddescription = 6

invalid_parameter = 7

undefind_error = 8

double_conversion = 9

stepl_not_found = 10

others = 11.

if sy-subrc = 0.

Put the screen value in the select-options

read table l_i_dynp into l_wa_dynp index 1." For single value

s_prog-low = l_wa_dynp-fieldvalue.

endif.
