Dynamic Table in ALV

[Former Member]

Hello experts,

is it possible to call an ALV via ( class cl_salv or fm REUSE_ALV_GRID_DISPLAY) with a dynamic table?

This dynamic table has for example one fix column for the material number and dynamic colums for additional data.

One material has 1 additional column, the other material has two additional columns.

So i need an ALV with 3 columns material add_data1 add_data2 (add_data2 of material one is empty this is ok).

To build an itab which can handle this is possible i know.

Hi,

Yes it is possible,

you can create a dynamic internal table using cl_salv_table_create=>create_dynamic_table.

Hi,

i can not find class cl_salv_table_create in my system. Is there a spelling error?

It is CL_ALV_TABLE_CREATE

Thanks

Field will be dispalyed with a blank value. Only this is possible.

Hello Benjamin,

Maybe you already found a solution for this, but if not (or for others looking for a solution), here is a sample program that creates, fills, and displays a dynamic table:

report ztpar_dynamic_salv.

parameters: p_colnr type i default 3.

start-of-selection.
  perform execute.

form execute.

  data t_table type ref to data.

** create dynamic table
  perform create_dynamic_table using p_colnr
                            changing t_table.

** fill dynamic table
  perform fill_dynamic_table changing t_table.

** display dynamic table
  perform display_table using t_table.

endform.

form create_dynamic_table using colnr type i
                       changing table type ref to data.
  data: lo_field type ref to cl_abap_typedescr,
        lo_struct type ref to cl_abap_structdescr,
        lo_table type ref to cl_abap_tabledescr.
  data: t_comp type cl_abap_structdescr=>component_table,
        l_comp like line of t_comp.

  lo_field ?= cl_abap_typedescr=>describe_by_name( 'CHAR10' ).
  do p_colnr times.
    move sy-index to l_comp-name.
    concatenate 'COLUMN' l_comp-name into l_comp-name.
    condense l_comp-name no-gaps.
    l_comp-type ?= lo_field.
    append l_comp to t_comp.
  enddo.

  lo_struct = cl_abap_structdescr=>create( p_components = t_comp p_strict = space ).
  lo_table = cl_abap_tabledescr=>create( lo_struct ).

  create data table type handle lo_table.
endform.

form fill_dynamic_table changing table type ref to data.
  field-symbols: <fs_table> type standard table,
                 <fs_line> type any,
                 <fs_field> type any.

  assign table->* to <fs_table>.
  do 5 times.
    append initial line to <fs_table> assigning <fs_line>.
    do.
      assign component sy-index of structure <fs_line> to <fs_field>.
      if sy-subrc ne 0.
        exit.
      endif.
      <fs_field> = sy-index.
    enddo.
  enddo.
endform.

form display_table using i_table type ref to data.
  data lo_alv type ref to cl_salv_table.

  field-symbols <fs_tab> type any table.

  assign i_table->* to <fs_tab>.
  try.
      cl_salv_table=>factory(
        importing
          r_salv_table = lo_alv
        changing
          t_table      = <fs_tab> ).
    catch cx_salv_msg.
      message 'Cannot display result!' type 'E'.
  endtry.

  lo_alv->display( ).
endform.

Best regards,
