In this part of the tutorial, you add more complex business logic to the business process that you designed and tested earlier. This part of the tutorial consists of the following steps:
You extract a list of items from the RFQ document received from a client and perform a set of activities once for each item in the list.
You design your business process to execute tasks in parallel. This step also includes instructions for designing your business process to interact with resources through controls and transform the data exchanged with those controls, as required.
You learn how to transform the price and availability data from untyped XML data to typed XML, and then combine the price and availability data (that is returned to the business process from several external services) in a single quote document.
You learn how to write business process data to a log by using a file control.
