Use Role References

In Service Studio you can use roles that are exposed by another eSpace or extension, called, in this context, a Producer. Simply add these roles as eSpace reference (Is an element exposed by a Producer eSpace or extension that, when referenced by a Consumer eSpace, is called an eSpace reference in its context. Once an eSpace reference, e.g. an action or entity, is added, you can use it anywhere in the Consumer eSpace but you cannot change its definition.) of your eSpace, called, in this context, a Consumer eSpace.

How to add a Role reference:

In the Consumer eSpace, launch the Add/Remove References window, select the Producer eSpace or extension in this window and then check the role that you want.

Once roles are added as references, you can use them in your eSpace:

In any action flow (Collection of elements that graphically implements the behavior of an action. You can have assign and control elements, exception handlers or you can invoke other actions. The elements are linked through Connectors.), by dragging the role related action from the Role folder (on the Logic Layer of the eSpace Tree), into the flow, just like any other action or
In any Web Screen, Human Activity, Send Message, and Wait for Message, by selecting the element and checking the Roles property that corresponds to the exposed role.

How Role References are Executed

The role that you added as a reference is checked in the context of the Consumer eSpace, that is, within the same database transaction.
