Change field on screen

[Former Member]

Hi,

I have a module pool requirement wherein i need to display one field as input field from user Lets say MATNR

and based on material number selected by user , there is one additional field on module pool lets say material description

which is purely display field. Now the requirement is that when user enter material number on screen then its corresponding

material description should automatically get displayed on screen.

Thanks

Hi

Check the below Code Snippet

DATA : from_f4.
" Just copy this and Execute this is Tested Code
PARAMETERS : matnr TYPE matnr,
             maktx TYPE maktx.

DATA : BEGIN OF itab OCCURS 0,
       matnr type matnr,
       maktx type maktx,
   END OF itab.
DATA : fmap TYPE TABLE OF dselc WITH HEADER LINE.

AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF screen-name = 'MAKTX'.
      screen-input = 0.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR MATNR." If it is a selection
*Screen
*else in PROCESS ON VALUE REQUEST

  SELECT A~MATNR B~MAKTX FROM MARA AS A INNER JOIN MAKT AS B
    ON A~MATNR = B~MATNR
    INTO TABLE ITAB UP TO 200 ROWS.

  fmap-fldname = 'MATNR'.
  fmap-dyfldname = 'MATNR'.
  APPEND fmap.
  fmap-fldname = 'MAKTX'.
  fmap-dyfldname = 'MAKTX'.
  APPEND fmap.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      ddic_structure         = 'ZMATNR11' " Create your Own Structure in SE11
" with only 2 fields (MATNR and MAKTX)
" We can use MAKT(so that we can avoid structure 
"creation in SE11)
" table but for unkonw reasons it is returning Junk 
"Chars at the end of Material description
      retfield               = 'MATNR' 
     dynpprog               = sy-repid
     dynpnr                 = sy-dynnr
     dynprofield            = 'MATNR'
     value_org              = 'S'
     display                = 'F' " This forces the F4 help for
    TABLES
      value_tab              = itab
     dynpfld_mapping        = fmap.

Write a PBO Module:

IF g_matnr IS NOT INITIAL.
 SELECT SINGLE maktx 
      FROM makt
      INTO g_maktx
    WHERE matnr EQ g_matnr
      AND spras EQ syst-langu.        
ENDIF.
