Dynamic internal table

[Former Member]

Hi,

I have created list box in the selection screen.In the list box Iam getting 10 characterstics values like(z_xx_che,z_xx_cof,z_xx_me.......) dynamically.

when user select the particular characterstic then it should display appropriate characterstics dynamically in the ALV layout.

first how it dynamically trigger the particular characterstic when user select the particular characterstic ?

please help me on this.

Try the below code.

-

---

DATA: itab_ref TYPE REF TO data,

tabname like RSRD1-TBMA_VAL," VALUE 'pa0001',

fields TYPE string,

where TYPE string.

PARAMETERS: p_tab TYPE tabname default 'pa0001',

p_pernr TYPE PERSNO.

CREATE DATA itab_ref TYPE STANDARD TABLE OF (p_tab)."(tabname).

FIELD-SYMBOLS: <itab> TYPE STANDARD TABLE,

<wa>.

ASSIGN itab_ref->* TO <itab>.

DEFINE dselect.

SELECT (&1) FROM (&2) INTO CORRESPONDING FIELDS OF TABLE &3 WHERE (&4).

END-OF-DEFINITION.

START-OF-SELECTION.

fields = 'PERNR'.

where = 'PERNR = ''00001001'''.

dselect fields p_tab <itab> where.

In the above code, pernr field is selected from the table, pa0001. So you can dynamically pass the table here, and pass the p_perne field dynamically to fields.

Hi,

use this cl_alv_table_create, here some exam:

DATA : BEGIN OF g_object,
         alv_table TYPE REF TO cl_alv_table_create,
         alv_data  TYPE REF TO data,
         data_fcat TYPE lvc_t_fcat,
         alv_fcat  TYPE slis_t_fieldcat_alv,
       END OF g_object.

FIELD-SYMBOLS : <table> TYPE STANDARD TABLE.

you have to create fcat manuelly,

  CREATE OBJECT g_object-alv_table.

  CALL METHOD g_object-alv_table->create_dynamic_table
    EXPORTING
      it_fieldcatalog           = g_object-data_fcat
    IMPORTING
      ep_table                  = g_object-alv_data
    EXCEPTIONS
      generate_subpool_dir_full = 1
      OTHERS                    = 2.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
               WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

  ASSIGN g_object-alv_data->* TO <table>.

at last :

  CALL FUNCTION 'LVC_TRANSFER_TO_SLIS'
    EXPORTING
      it_fieldcat_lvc         = g_object-data_fcat[]
    IMPORTING
      et_fieldcat_alv         = g_object-alv_fcat[]
    EXCEPTIONS
      it_data_missing         = 1
      it_fieldcat_lvc_missing = 2
      OTHERS                  = 3.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
   EXPORTING
     i_callback_program                = sy-repid
     i_callback_pf_status_set          = 'MY_PF_STATUS'
     i_callback_user_command           = 'MY_USER_COMMAND'
     is_layout                         = ls_layo
     it_fieldcat                       = g_object-alv_fcat[]
*   IT_SORT                           =

*   IS_VARIANT                        =
   TABLES
     t_outtab                          = <table>
   EXCEPTIONS
     program_error                     = 1
     OTHERS                            = 2.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
