Remove optinos in user decision task dinamically

Question

Hi all,
I have an user decision task wich have several options. I want to remove (or deactivate) some of these options dinamically or under some conditions...
Do you know how can i do it?
May be it's possible to do with a program exit but i don't find any method in the class for do that.
Thanks in advance.

Hi,
Finally, I had to do it. I put the steps in case anyone is interested:
- Create a Decision Task in workflow builder. Replace the Task used in Control tab by a custom one. You need to create a copy of the standard task 00008267. In my case I've created the task 99000001.
- The FM to get the options and texts is SWU_GET_DECISION_TEXT_TITLE. We need to create an enhancement point at the end of this FM. I've created a method in a custom class to embed all my code:
TRY.
  CALL METHOD zcl_im_wf_dec_task=>zz_mod_decision_task
    EXPORTING
      wiid             = wiid
    changing
      ct_decision_text = decision_text[].
CATCH cx_root.
ENDTRY.
- This method has the following parameters:
WIID                     TYPE SWW_WIID
CT_DECISION_TEXT     TYPE ANY TABLE
With the following code you can change the description of the options you want or delete some options dinamically:
DATA: l_wi_handle  TYPE REF TO if_swf_run_wim_internal,
      lo_wi_dialog TYPE REF TO cl_swf_run_wim_dialog,
      lo_container TYPE REF TO if_swf_cnt_container,
      ls_wi_head   TYPE sww_wihead,
      lv_key       TYPE sww_wi2obj-instid,
      lv_bstyp     TYPE ebstyp.
FIELD-SYMBOLS: <ls> TYPE ANY.
* Obtain the header:
TRY.
    CALL METHOD cl_swf_run_wim_factory=>find_by_wiid
      EXPORTING
        im_wiid     = wiid
      RECEIVING
        re_instance = l_wi_handle.
    lo_wi_dialog ?= l_wi_handle.
    ls_wi_head = lo_wi_dialog->if_swf_run_wim_internal~m_sww_wihead.
  CATCH cx_swf_run_wim .
  CATCH cx_root.
ENDTRY.
* Read the container (if you want...):
TRY.
    CALL METHOD lo_wi_dialog->if_swf_run_wim_wfm~get_wi_container
      RECEIVING
        re_container = lo_container.
  CATCH cx_swf_run_wim .
ENDTRY.
* Read the Key:
SELECT SINGLE instid INTO lv_key
FROM sww_wi2obj
WHERE top_wi_id EQ ls_wi_head-top_wi_id.
* In this example is a workflow for PO;
SELECT SINGLE bstyp INTO lv_bstyp
FROM ekko WHERE ebeln EQ lv_key.
* Depending on the Task;
CASE ls_wi_head-wi_rh_task.
*  Authorize  
  WHEN 'TS99000001'.
    LOOP AT ct_decision_text ASSIGNING <ls>.
*       The first 4 characters are the number of the option.
*       The following characters are the description.
*       Delete an option;
      IF <ls>(4) EQ '0001' AND lv_bstyp EQ 'F'.
        DELETE ct_decision_text INDEX sy-tabix.
        CONTINUE.
      ENDIF.
*       Change the description:
      IF <ls>(4) EQ '0002'.
        IF lv_bstyp EQ 'K'.
          <ls>+4 = 'Authorize'.
        ELSE.
          <ls>+4 = 'Continue with the process'.
        ENDIF.
      ENDIF.
    ENDLOOP.
ENDCASE.
