Hi,

You must create a custom search help. This new search help must contain a reference to table in dictionary in which your fields are linked one to each other with this search help.

Let's say you have a transparent table ZTABLE:

ZTABLE-FIELD1 -> Search help ZH_MY_HELP

ZTABLE-FIELD2 -> Search help ZH_MY_HELP

In search help ZH_MY_HELP, you defined this ZTABLE as your reference table, and FIELD1 and FIELD2 are explicitly mentioned as fields for search.

Doing this, when you define in your selection screen:

PARAMETERS: param1 TYPE ZTABLE-FIELD1,

param2 TYPE ZTABLE-FIELD2.

Values from param2 will depend of values from param1, when pressing F4. This is what I think your "read value from selection screen, without pressing enter" problem is.

Best regards!

Hi,

Try below code.

TABLES: MARA.

types: begin of ty,

          matnr type matnr,

         werks type werks_d,

        end of ty.

data: it2 type standard table of dselc,

       wa2 type dselc.

data: it type standard table of ty,

       wa_return type ddshretval,

       i_return type standard table of ddshretval,

       repid type sy-repid,

       dynnr type sy-dynnr.

parameters:

          p_matnr   type mara-matnr,

          p_werks    type marc-werks.

SELECT-OPTIONS: S_BUKRS FOR MARA-MATNR.

at selection-screen output.

**  loop at screen.

**    if screen-name = 'P_WERKS'.

**      screen-input = '0'.

**      screen-DISPLAY_3D = 'X'.

**      modify screen.

**    endif.

**  endloop.

at selection-screen on value-request for p_matnr.

   repid = sy-repid.

   dynnr = sy-dynnr.

   select matnr werks

               from marc up to 20 rows

   append wa2 to it2.

   append wa2 to it2.

   call function 'F4IF_INT_TABLE_VALUE_REQUEST'
