assigning a value to container element in rule defination

I am using a rule to determine an actual agent. I am using a function module containing actor_tab and ac_conatiner in TABLES parameter. the agent determined is appended to internal table actor_tab. I want this agent to be available in a container element(say: APPROVER) to use it further. I am trying to assingn the agent value to container element using macro swc_set_element ac_container 'APPROVER' agent-name. But its not working...any other way to assgn this agent to the container element. Bindings from workflow container to rule container are proper.
