Workitem in Method

Hi Experts,

How i can get the current Workitem Id and Workitem Text in my method.

I am able to get the Main Workflow id in my Method.

Through this Main Workflow id i can get the current Workitem Id using FM or through tables.

Is there any other way to get the Workitem Id ?

Using SWC_GET_ELEMENT statements in my method.

I am using swc_get_element container '_Workitem.WorkitemId' l_wi_id.

swc_get_element container '_Workitem.WorkitemShortText' l_wi_text.

But this is not working Please suggest.

Thanks in Advance....
