Scheduler 
You use the scheduler for the load process to define the parameters for the data transfer to a particular DataSource. You determine what sort of data (flow data, master data, texts, or hierarchies), from which DataSource, and from which source system are requested and written to the BI entry layer, the Persistent Staging Area.
You create an InfoPackage for the data request in the scheduler for a DataSource. You determine the parameters for scheduling the data request for a DataSource in the InfoPackage
We recommend including InfoPackages in the process chains that automate the processes in the Data Warehouse.
