Using an Explicit Transaction

The following scenarios illustrate two ways to use an explicit transaction and achieve the same result. In these scenarios, a business service processes a sales order. Inventory records are updated when each record is processed instead of waiting until the end of the sales order processing to update the inventory records. In each scenario, if an error occurs before the sales order process is completed and committed, an exception message is sent to the caller, and updates that were made to the inventory records are rolled back.
