External data in processes
In order to control external data access in processes, a connection to the respective external system must first be created in the "Integration" module. Then integrate the connection per external data group in an application.
You can find out how to create a connection and configure external data groups in applications here in the help for the respective connector.
Information on implementation in the process can be found here:
