Process chains can be scheduled as processes in additional process chains. These are called metachains. If the process chain that you want to execute is in the metachain, use the Local Process Chain process type.
A local process chain consists of processes that are scheduled in the same system as the metachain.
You use a local process chain to schedule a process chain as a process of a metachain.
In addition to local process chains, you can also schedule remote process chains as processes in a metachain. A remote process chain calls a process chain in another system. This is executed in the other system.
