Fig. 8.7 Decomposition of task Create Purchase Order and set up of variable POrder

The details of a net decomposition (i.e., its label and variables) can be set
up through the Update net detail... dialogue, under the Net menu, whereas task
decompositions can be created via the Select Task Decomposition dialogue and
modified via the Task Decomposition detail..., both available from the task’s context-
menu. Figure 8.7 shows the decomposition of task Create Purchase Order.Here
variable PO Manager is of simple data type string to contain the username of
the purchase order manager, while POrder has been assigned the complex type
PurchaseOrderType as defined in Fig. 8.6.
The Editor supports the workflow designer in setting up inbound and outbound
mappings to specify how data is transferred between net and task variables. In
