Hi Ravi,
You were able to program the function module but you are not able to find out why the exception is raised? This sounds a bit strange to me, or do you want us to give an answer in stead of searching for one yourself?
If you didn't create these container elements in the workflow you can't use them, and it could even be that that is why your exception is raised. By putting them in a container which is used when starting the workflow, they will not be automatically created in your workflow.
And to be more up to date use FM SAP_WAPI_START_WORKFLOW as Arghadip suggested.
