Container problems!

Question

I made a workflow with a task, which sends an email with a material. For this I created an element in the container called z_matnr, type matnr. I set it to be import-export.
In the header of the email i have &Z_MATNR&.
The event that is triggering the program is called Z_EVENT, and is made for the object BUS2032. I dont think that is a problem. I just wanted to create an event that is starting the workflow.
I made a program. The mail is sent but the material is empty. Why is that?
Here is the code:
{INCLUDE <cntn01>.
DATA:    lt_message TYPE TABLE OF swr_messag,
         gt_container TYPE TABLE OF swr_cont,
         gs_container LIKE swr_cont.
gs_container-element = 'Z_MATNR'.
gs_container-value = '10'.
append gs_container to gt_container.
CALL FUNCTION 'SAP_WAPI_CREATE_EVENT'
  EXPORTING
    object_type             = 'BUS2032'
    object_key              = 'Z12345'
    event                   = 'Z_EVENT'
   COMMIT_WORK             = 'X'
TABLES
   INPUT_CONTAINER         = gt_container
   MESSAGE_LINES           = lt_message.
FORM append_container  USING    value(p_0456)
                              p_ls.
  gs_container-element = p_0456.
  gs_container-value   = p_ls.
  APPEND gs_container TO gt_container.
ENDFORM.                    }

Hi
By looking at all your posts I felt like you are still woring on your assignment... well you are trying to start workflow by using the events. right?
now the check list for starting workflow by using events are
1. Make sure you have defined the start event in the basic data of the workflow.  Or atleast make sure you ahve made an entry in the SWE2 transaction with the respective workflow tempalte number and business obect in your case 'BUs1001 and the event is Z_EVENT.
2. Once this is done the next thing is you need to check whether the workflow is actring as receiver or not it can be done by using the txn SWUE.
3. Now inorder to pass soem thing to workflow or if you want to pass parameters of event to event container to workflow contianer make sure you ghave defined the binding between event container and workflow container in the basic data of the workflow. or from PFTC txn.
4. By looking at your code I feel like you want to pass the material object  to workflow container. Now when you are starting workflow by using a event One thing is sure that you do not have to instatiate the BOR all you have to do is pass th object name you want to instantiate and the object key.
data:
begin of lv_object_instance,
objtype type swo_objtyp,
objkey type swo_typeid,
end of lv_object_instance.
swc_container lt_wf_cont.
swc_create_container lt_wf_cont.
lv_object_instance-objtype = 'MATERIAL'.
lv_object_instance-objkey = '000000000000000011'.
swc_set_element lt_wf_cont 'MATERIAL' ''000000000000000011'.
"<------- lt_wf_cont-element = 'Z_BUS1001'.
"<--------lt_wf_cont-value = lv_object_instance.  " <---- Do not require like this.
"<------append lt_wf_cont.
CALL FUNCTION 'SAP_WAPI_CREATE_EVENT'
EXPORTING
object_type = 'Z_BUS1001'
object_key = 'Z12349'
event = 'Z_EVENT'
COMMIT_WORK = 'X'
TABLES
INPUT_CONTAINER = lt_wf_cont
MESSAGE_LINES = lt_message.
