Pass BO as parameter to RH_GET_ACTORS.

Hi all,

I have a requirement to get the agents for the standard rule "20000027" (PO workflow agents).

But the rule accepts Purchase order business object (BUS2012) as container parameter.

Now i  need to call the FM RH_Get_actors in abap to determine the agents and if no agents found then do subsequent steps.

But i am unable to pass business object as parameter to the FM.

Kindly advise.

Regards

Suman
