Attachment to _Attach_Objects in user dicision step

Question

hi friends
  I need to attach the PDF to my work item (user dicision step). I know this has been discussed many times. I have read all most all the forms. I am still facing the problem. I have function module ZPDF which converts smart form into PDF and putting the PDF in my BINFILE of type SOLIX. Now i need to attach this BINFILE to my user dicision AttachObjects. In my method am calling ZPDF in my OBJECT ZBUS2089 method wiattachment. I know SOFM instance to be created. But how to create the SOFM INSTANCE?. i used this syntax
DATA : ls_sofm_key type SWOTOBJID-OBJKEY.
DATA: lr_sofm TYPE swc_object.
SWC_CREATE_OBJECT lr_sofm 'SOFM'  ls_sofm_key.
CALL METHOD t_container->if_swf_ifs_parameter_container~set
EXPORTING
name = 'Attachments'
value = lr_sofm
IMPORTING
returncode = ls_subrc.
Its showing the error t_container is not know there is similiar name container.
So i changed  t_container to container.
But its show there is no reference. what i need to do now.how to get the reference.
IF this is not the correct way to proceed then tell me the write way to use.
My ultimate aim to fill my workflow container with Attachment of type SOFM and in the binding
attachment --> AttachObject.
I want to fill my WF container with SOFM instance.

Hi pavan
  In my method i have written the code has above i have created attribute with SOFM with type SOFM. But i when i debug it comes excatly to the last line and giving me a dump.
   IF lv_return = 0.
        lv_objtkey = lv_att_id.
        lv_objsofm = 'SOFM'.
        swc_create_object bo_sofm lv_objsofm lv_objtkey.
  SWC_SET_ELEMENT CONTAINER 'LV_ATT_ID' LV_ATT_ID.
  SWC_SET_ELEMENT CONTAINER 'SOFM' lv_objtkey.
      ENDIF.
i have put this container element inside the if statement. I am getting a dump.
Dump.

    The statement
