Selects the first location available among one or more locations listed in a routing block. Specifying multiple First Available routings in a routing block has the same effect as specifying a First Available routing followed by one or more ALTERNATE routings. An example of using the First Available rule in a routing block is given below.
The First Available rule is the default rule when defining the initial routing in the Process Editor. In this case, the First Available routing can be interpreted to be the "primary" routing.
