Allocation simulation by function module/BAPI

Question

Hello experts,
I would like to simulate an allocation (distribute quantities to plants) (SAP component LO-MDS-AL). For this Iu2019m looking for an appropriated function module which I set the article
number, plants, the allocation rule and the quantity to be distributed to the plants,
The result should only be simulated; no document should be created.
Which function module can I use for this?
Thank you for your information.
Best regards,
Kurt.

* Get plants for distribution:
  call function 'WAUF_READ_DISPATCHERRULE'
    exporting
      im_key                    = ls_key
      im_pincr                  = 1
      im_sbeln                  = iv_sbeln
      im_prefetch_kna1          = 'X'
      im_prefetch_wrf1          = 'X'
      im_prefetch_material_data = 'X'
      im_material               = iv_material
      im_prefetch_wlk1          = space
    importing
      ex_svko                   = ls_svko
    tables
      ex_figr                   = lt_figr
      ex_filn                   = lt_filn
    exceptions
      ar_nicht_vorhanden        = 1
      ar_pos_nicht_selektierbar = 2
      clint_convert_error       = 3
      figr_existiert_nicht      = 4
      others                    = 5.
The table lt_figr contains the plants assigned in the allocation; this table can be changed (remove some plants which are not necessary).
* Simulate allocation:
  call function 'WAUF_DETERMINE_QUANTITIES'
    exporting
      im_quantity_to_split           = lv_to_split
      im_alloc_tbl                   = lv_alloc_tbl        " Dummy
      im_alloc_tbl_item              = lv_alloc_tbl_item   " Dummy
      im_material                    = iv_material
      im_base_unit                   = 'CU'
      im_item_category               = 'ZB'
      im_quantity_simulation         = lv_quantity_simulation
      im_rounding                    = ls_svko-rundg
      im_split_remainder             = ls_svko-restv
      im_min_max_qty                 = lv_min_max_qty
    importing
      ex_quantity_splitted           = lv_quantity_splitted
    tables
      im_ex_stores                   = lt_filn
      im_ex_store_groups             = lt_figr
    exceptions
      quantity_simulation_invalid    = 1
      rounding_invalid               = 2
      split_remainder_invalid        = 3
      min_max_qty_invalid            = 4
      stores_storegroup_inconsistent = 5
      sum_quotas_initial             = 6
      call_functionmodul_round       = 7
      planned_qty_less_min_qty       = 8
      planned_qty_greater_max_qty    = 9
      arithmetic_errors              = 10
      others                         = 11.
