Shared Variable
A Shared Variable resource allows you to share data across process instances. All process instances can read and update the data stored in a shared variable.
This resource is useful if you want to marshal data across process instances or if you want to make a common set of information available to all process instances. For example, you may have a set of approval codes for incoming orders that change daily for security purposes. You can create a shared variable to hold the approval codes and create one process definition for setting the codes. You can then retrieve the shared variable in all processes that require the current approval codes.
