List output in ALV grid

Question

Hi all,
I need the list output of  one program in my program in a grid(single column).
I am doing the below..
  TYPES: BEGIN OF tp_ascitab ,
                line(150),
              END OF tp_ascitab.
  DATA:  dt_ascitab   TYPE TABLE OF tp_ascitab,
         ds_ascitab   TYPE tp_ascitab.
    SUBMIT zlist_program    WITH p-gmn EQ matno
    WITH p-plant EQ plant
    EXPORTING LIST TO MEMORY
    AND RETURN.
    CALL FUNCTION 'LIST_FROM_MEMORY'
      TABLES
        listobject = gmn_info_tab
      EXCEPTIONS
        not_found  = 1
        OTHERS     = 2.
    CALL FUNCTION 'LIST_TO_ASCI'
      TABLES
        listobject = gmn_info_tab
        listasci   = dt_ascitab.
    IF sy-subrc <> 0.
      MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
              WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
    IF dg_gridcont IS INITIAL.
Create controls
      CREATE OBJECT dg_gridcont
        EXPORTING container_name = 'GRID_CONT'.
    ENDIF.
    CREATE OBJECT dg_grid
              EXPORTING i_parent = dg_gridcont.
    ds_layout-no_hgridln = 'X'.
    ds_layout-no_toolbar = 'X'.
    CALL METHOD dg_grid->set_table_for_first_display
      EXPORTING
        is_layout       = ds_layout
      CHANGING
        it_fieldcatalog = dt_fcat[]
        it_outtab       = dt_ascitab.
The table dt_ascitab has data in correct format until it is passed to grid.
After that, there is change in alignmentt. The grid output has data with
improper alignment. Could anyone help me with this.
thanks,
Keerthi.

Hi Keerthi,
Try Using following FM before Method 'set_table_for_first_display'
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
         EXPORTING
              i_buffer_active        = ' '
              i_structure_name       = 'structure in which format u need output'
              i_client_never_display = 'X'
              i_bypassing_buffer     = 'X'
         CHANGING
              ct_fieldcat            = dt_fcat[]
         EXCEPTIONS
              inconsistent_interface = 1
              program_error          = 2
              OTHERS                 = 3.
Hope, it will help u.
