Hi Balu,

Do you want to display the description as a comment with the parameter??

Like :

Material Number 000001, On pressing enter the desc. comes in line as:

Material Number 000001 Material 1

Thanks and Best Regards,

Vikas Bittera.

Sure, but you should need to modify the Search Help....Or you can use this FM...

<b>F4IF_INT_TABLE_VALUE_REQUEST</b>

You can do it like this.




report zrich_0002 .

selection-screen begin of line.
selection-screen comment (20) matnr.
parameters: p_matnr type mara-matnr.
selection-screen comment (40) maktx.
selection-screen end of line.

at selection-screen output.
matnr = 'Material Number'.
if maktx is initial.
  select single maktx into maktx
         from makt
        where matnr = p_matnr
          and spras = sy-langu.
 endif.


at selection-screen on value-request for p_matnr.


data: dynfields type table of dynpread with header line.
data: return type table of ddshretval with header line.


  call function 'F4IF_FIELD_VALUE_REQUEST'
       exporting
            tabname           = 'MARA'
            fieldname         = 'MATNR'
            dynpprog          = sy-cprog
            dynpnr            = sy-dynnr
            dynprofield       = 'P_MATNR'
       tables
            return_tab        = return
       exceptions
            field_not_found   = 1
            no_help_for_field = 2
            inconsistent_help = 3
            no_values_found   = 4
            others            = 5.

  read table return with key fieldname = 'P_MATNR'.

* Add it back to the dynpro.
  dynfields-fieldname = return-retfield.
  dynfields-fieldvalue =  return-fieldval.
  append dynfields.


  clear dynfields.
  dynfields-fieldname = 'MAKTX'.
  call function 'CONVERSION_EXIT_ALPHA_INPUT'
    exporting
      input         = return-fieldval
    IMPORTING
      OUTPUT        = p_matnr.

  select single maktx into dynfields-fieldvalue
         from makt
        where matnr = p_matnr
          and spras = sy-langu.
  append dynfields.


* Update the dynpro values.
  call function 'DYNP_VALUES_UPDATE'
       exporting
            dyname     = sy-cprog
            dynumb     = sy-dynnr
       tables
            dynpfields = dynfields
       exceptions
            others     = 8.

start-of-selection.

This will also handle if you do F4 help on the MATNR field, and select a material, the description will be filled in automatically.

Ok, so just modify this event as you see below.



at selection-screen output.
clear maktx.
matnr = 'Material Number'.
  select single maktx into maktx
         from makt
        where matnr = p_matnr
          and spras = sy-langu.

  SELECT SINGLE MAKTX INTO MAKTX
         FROM MAKT
        WHERE MATNR = P_MATNR
          AND SPRAS = SY-LANGU.

<b>  IF SY-SUBRC <> 0.
    CLEAR MAKTX.
  ENDIF.</b>
