REUSE_ALV_FIELDCATALOG_MERGE not working internal table

Hi, REUSE_ALV_FIELDCATALOG_MERGE not working gt_fieldcat[] return is intial my code is like below

Hi

It depends on how te internal table is defined:

the function module REUSE_ALV_FIELDCATALOG_MERGE scans the program in order to get the definition of the internal table, but sometimes it can't get the definition, it's better to use the "old way" to define an internal table

I suppose the logic for scanning (used by REUSE_ALV_FIELDCATALOG_MERGE) doesn't manage all ways to define an internal table.

Perhaps there's a Sap Note

Hi,

In place of using old-fashioned REUSE functions for building ALV grids, you should use CL_SALV classes.

Basically, you can display easily the contents of a table with this code (wt_display is your internal table).

If needed you can change attributes of the columns, I put a simple example here.

DATA: ob_table   TYPE REF TO cl_salv_table,
      ob_column  TYPE REF TO cl_salv_column.

  TRY.
      cl_salv_table=>factory( IMPORTING r_salv_table = ob_table
                               CHANGING t_table      = wt_display ).
    CATCH cx_salv_msg.
  ENDTRY.

  IF ob_table IS BOUND.
*   Screen status
    ob_table->set_screen_status( EXPORTING report        = 'SAPLKKBL'
                                           pfstatus      = 'STD_LIGHT_FULLSCREEN'
                                           set_functions = ob_table->c_functions_all ).

*   Optimize columns
    ob_table->get_columns( )->set_optimize( ).

*   Special column: to be hidden
    ob_column = ob_table->get_columns( )->get_column( columnname = 'MY_FIELD_NAME' ).
    IF ob_column IS BOUND.
      ob_column->set_technical( ).
    ENDIF.

*   Display
    ob_table->display( ).
  ENDIF.
