Part 4: Add invocations and logic to the top-level flow
In this part you will finish constructing the top-level flow, CatalogOrder.seqflow,
by adding logic, an invocation of the recorded flow CheckItemAvailability.seqflow,
and an invocation of a nonterminal application.
Step 4.1: Invoke the recorded flow from the top-level flow In this step you will: (a) modify the
Invoke node Step0 in the top-level flow CatalogOrder.seqflow so that Step0 invokes
the recorded flow CheckItemAvailability.seqflow;
(b) copy data from the input message of the top-level flow into working
variables; and (c) add a new Assign node to the top-level flow that
retrieves the result returned by the recorded flow CheckItemAvailability.seqflow.
Step 4.5: Set the output parameters of the flow CatalogOrder
In this topic you will store the output parameters returned
by the nonterminal application DFH0XCMN (which
is invoked by the Invoke nonterminal node PlaceOrder in CatalogOrder.seqflow) into
the output structure of the flow CatalogOrder.
