A branch is
a set of activities that the process executes. Process diagrams
can include one or more branches. When you create a process and
add elements to the process diagram, the elements belong to the
default branch, called the main branch.
The use of multiple branches allows you to implement different
behaviors for different parts of the process. You add branches to
a process by drawing routes from activities and other elements to
gateways. (See Adding branches using gateways.) After you add a branch to a gateway,
you can configure its branch type.
The branch type also dictates the type of operations that can
be added. For more information about branch types, see Transactions.
At run time, operations in a branch are executed sequentially.
When an operation is running, no other operation in the branch is
running. When the operation is completed, the next operation is
executed. To execute multiple operations simultaneously, they need
to belong to different branches inside gateways.
The type of the main branch is specified when the process is
created and can be changed in the properties of the process version.
