Exporting parameter of type table in Method of a Class

Hi Experts,

I want to pass an internal table from my method in ABAP class to a workflow.

For thi spurpose i have cretaed a parameter of type table in the method.

My problem is that i am not able to bind this to a workflow/task container.

I can see all the other parameters of the method in thw workflow while binding except for the parameter of type table ( i.e internal table ).

Any idea ?

Thanks,

Radhika.
