Alv overlapped for multiple input

[former_member266878]

Hi experts,

I add a additional tab in me22n to display alv but whenever i am giving multiple order in same session its overlapped.Find the attachement below.

SELECT ebeln
          belnr
          menge
          dmbtr FROM ekbe INTO TABLE it_ekbe WHERE ebeln EQ i_ekpo-ebeln.
   SORT it_ekbe DESCENDING BY belnr.
   CLEAR sy-dynnr.
*IF sy-subrc EQ 0.
   LOOP AT it_ekbe INTO wa_ekbe .
     wa_alv-belnr = wa_ekbe-belnr.
     wa_alv-menge = wa_ekbe-menge.
     wa_alv-dmbtr = wa_ekbe-dmbtr.
     lv_u_price = wa_ekbe-dmbtr / wa_ekbe-menge.
     wa_alv-u_price = lv_u_price.
     APPEND wa_alv TO it_alv.
     SORT it_alv DESCENDING BY belnr.

   ENDLOOP.

*IF it_alv IS   NOT INITIAL.
   CLEAR wa_fcat.
   wa_fcat-col_pos = 1.
   wa_fcat-fieldname = 'BELNR'.
   wa_fcat-tabname = 'IT_ALV'.

   wa_fcat-tabname = 'IT_ALV'.
   wa_fcat-coltext = 'UNIT PRICE'..
   APPEND wa_fcat TO it_fcat.
   CLEAR wa_fcat.

I don't understand what you mean: "multiple order in same session it's overlapped" ?

Could you explain step by step?

[former_member266878]

HI rossi,

In ME22N transaction ALV display against PO Its display good for first time but whenever changing the po the new alv gets overlapped with previous one though i used Refresh_table_display.

the written code is given above and the ALV in the attachment.

[Sandra_Rossi]

oh okay. It's a very frequent error. It's because you create a new instance of the container/ALV every time, without freeing the previous one, so the first non-freed control is always displayed. Use the FREE method (that's not the FREE statement) to free a control.

[former_member266878]

hi rossy,

I Used that but not working

CALL METHOD o_alv->free
           EXCEPTIONS
             cntl_error        = 1
             cntl_system_error = 2
             OTHERS            = 3.

         CALL METHOD o_cust->free
           EXCEPTIONS
             cntl_error        = 1
             cntl_system_error = 2
             OTHERS            = 3.
*      flag = 'X'.
         FREE o_cust.
         FREE o_alv.

*    LEAVE TO TRANSACTION 'ME22N' AND SKIP FIRST SCREEN.
         CLEAR : o_cust , o_alv .
         REFRESH : it_fcat.

[Sandra_Rossi]

I can't say anything else than you have to make sure by debug what happens exactly: if a control is created, it must be followed by a free. A control must not be created sucessively twice without having been freed between.
