To load data, you need two process chains: The InfoPackage that is used to supply the BW entry layer (Persistent Staging Area) with data, and the data transfer process that is used to supply a persistent storage area in BW (InfoProvider and Open Hub Destination) with data.
More information: Scheduler.
More information: Data Transfer Process.
When an InfoPackage is executed, the data is transferred from a source system to BW. When a data transfer process is executed, the data in BW is distributed to a persistent storage area in your data flow. You can use monitors to keep an eye on the transfer processes.
