Tip

Fast deletion of SAP table content

If a table has millions of records, full deletion becomes time consuming. Try this tip when you need to delete data quickly -- it works in seconds.

Editor's note: This tip works on an SAP 4.6C, WAS620 and WAS640 system (i.e., all currently suppported SAP platforms). Note that it is a tricky function that should only be used by programmers who know what they are doing.

* Use function from SE14

        call function 'DD_DATABASE_UTILITY'
             exporting
                  fct                     = 'MDF'
                  obj_name                = 'TABLE_NAME'
                  obj_type                = 'TABL'
                  exec_modus              = 'S'
             importing
                  subrc                   = sl_subrc
             exceptions
                  unexpected_error        = 1
                  unsupported_function    = 2
                  unsupported_obj_type    = 3
                  table_is_locked_by_tcnv = 4
                  authority_check_failed  = 5
                  abort_function          = 6
                  conversion_error        = 7
                  others                  = 8.

        if sl_subrc = 0 and sy-subrc = 0.
          write:/ '&1', '- Table Deleted OK'.
          commit work and wait.
        else.
          sl_status = 1.                          "Deletion Failed
          write:/ '&1', '- Table Deletion FAILED'.
        endif.
