REUSE_ALV_FIELDCATALOG_MERGE new field missing

[Former Member]

Hi guys,

I'm adding one more column to be displayed on an old existing program that uses REUSE_ALV_FIELDCATALOG_MERGE to generate the ALV fieldcat.

DATA : BEGIN OF itab OCCURS 0,
  matnr LIKE eina-matnr,
  extwg LIKE mara-extw,
  matkl LIKE mara-matkl,
  mtart LIKE mara-mtart,
  maktx LIKE makt-maktx,
  lifnr LIKE eina-lifnr,
  wglif LIKE eina-wglif,
 {color:red}idnlf like eina-idnlf,          " <---------new field{color}
  name1 LIKE lfa1-name1,
  profl LIKE mara-profl,
 END OF itab.

  CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
    EXPORTING
      i_program_name         = sy-cprog
      i_internal_tabname     = 'ITAB'
      i_client_never_display = ''
      i_inclname             = sy-cprog
*      i_bypassing_buffer     = 'X'
    CHANGING
      ct_fieldcat            = t_cat
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.

I've added in a new field inside the ITAB internal table, but it wouldn't appear in the t_cat, only all the old fields will appear. What have i done wrong?

Hi,

Please check Fieldcat Internal table which is passed into Display function module.

Thanks in advance,

This is the t_cat I receive after running through the FM.

ROW_POS     COL_POS     FIELDNAME                      TABNAME
         0 |         1                    |MATNR                         |ITAB               <
         0 |         2                    |EXTWG                         |ITAB               <
         0 |         3                    |MATKL                         |ITAB               <
         0 |         4                    |MTART                         |ITAB               <
         0 |         5                    |MAKTX                         |ITAB               <
         0 |         6                    |LIFNR                         |ITAB               <
         0 |         7                    |WGLIF                         |ITAB               <
         0 |         8                    |NAME1                         |ITAB               <
         0 |         9                    |PROFL                         |ITAB               <

As you can see, IDNLF is missing in t_cat.

Thanks for helping

Hi,

This issue with ALV buffer: when you change field catalog it is not always updated immediately. To refresh the buffer you can run report BALVBUFDEL or BCALV_BUFFER_DEL_SHARED (I do not remember the difference and so run both to be sure ). ....

If you have any variant ,Please dletete the variante and try.
