Beas Service Layer - Delete Workorder Routing

Hi,

is it possible to execute a Service Layer delete request with dynamic parameters in Beas Script?
I've tried different approaches, but none of them worked.

Example:

b.delete=WorkorderRouting(<ll_belnr>, <ll_belposid>, <ll_posid>)

I get the following error:
-1 Text: <-not allowed sign '<' between arguments!{}

Can someone tell me how to correctly pass parameters?

Thank you
