Method and task Binding issue

[srinivas]

Hi Experts,

Below is the piece of code extracted from SWO1 from a custom object.

BEGIN_METHOD GETITEMS CHANGING CONTAINER.
types:begin of st_matnr,
      matnr   type matnr,
      end of st_matnr.
data:lt_vbap    type table of vbap,
     lw_vbap    type vbap,
     lt_matnr  type table of mara,
     lw_matnr   type st_matnr,
     lw_vbeln   type vbeln,
     vbeln_cont  type swcont.
*     matnr_cont  type table of swcont.
swc_get_element CONTAINER 'lw_vbeln' lw_vbeln.
select * from vbap into table lt_vbap
where vbeln = lw_vbeln.
loop at lt_vbap into lw_vbap.
lw_matnr-matnr = lw_vbap-matnr.
append lw_matnr  to lt_matnr.
endloop.
swc_set_table CONTAINER 'matnr_cont' lt_matnr.
end_METHOD.

I need to export the lt_matnr to my workflow template.Could some one help me
in binding lt_matnr to WF template.Thanks in advance.
