Problem when processing an action

Dear developers,

actually i have the problem to change the status of an crm-order by a customer programm, so i can't use the customizing in spro (action profile and actions).

For processing an action i use the function modules CRM_ACTION_GET_TOOLBAR_IL to get the toolbar actions and the function module CRM_ACTION_PROCESS_IL to process the action.

Agter prcessing the action i get the following error in the method CL_METHODCALL_PPF~SET_SAVE_LOG

    "UNCAUGHT_EXCEPTION" "CX_OS_OBJECT_NOT_FOUND"

    "CL_TRIGGER_PPF================CP" bzw.

"CL_TRIGGER_PPF================CM001"

    "IF_OS_STATE~HANDLE_EXCEPTION"

Here's the source code of my program:

Data: LT_ACTION_OBJ type CRMT_ACTION_OBJ_TAB.

Data: L_ACTION_obj like line of lt_action_obj.

Data: LT_ACTION_FLD type CRMT_ACTION_TABLE_TAB.

Data: L_ACTION_FLD like line of lt_action_fld.

CALL FUNCTION 'CRM_ACTION_GET_TOOLBAR_IL'

    IV_REF_GUID               = '4664EDDFEE3A5EFDE1000000C0A8674D'

    ET_ACTION_OBJ             = LT_ACTION_OBJ

    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.

Data: IT_ACTION_OBJ type PPFTACTV.

Data: l_action_obj_ref like line of l_action_obj-action_ref.

Read table lt_action_obj index 1 into l_action_obj.

Read table l_action_obj-action_ref index 1 into l_action_obj_ref.

append l_action_obj_ref to IT_ACTION_OBJ.

CALL FUNCTION 'CRM_ACTION_REFRESH_IL'.

CALL FUNCTION 'CRM_ACTION_PROCESS_IL'

  EXPORTING

    IT_ACTION_OBJ         = IT_ACTION_OBJ

    IV_ACTIVATE           = 'X'

    IV_EXECUTE            = ''

    IV_DELETE             = ''

    PARAMETER_ERROR       = 1

    ERROR_OCCURRED        = 2

    OTHERS                = 3.

CALL FUNCTION 'CRM_ACTION_PROCESS_IL'

  EXPORTING

    IT_ACTION_OBJ         = IT_ACTION_OBJ

    IV_ACTIVATE           = ''

    IV_EXECUTE            = 'X'

    IV_DELETE             = ''

    PARAMETER_ERROR       = 1

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

ENDIF.

Do you have an idea how to solve this problem?

Best regards,
