Managing the Process Flow 
You can configure the various upload stages of the data upload process. These upload stages include, for example, the following:
Data acquisition
Quality validation
Data propagation
Data enrichment
Data harmonization
You configure the upload stages by assigning them to individual steps in Customizing for Cross-Application Components under 
Demand Data Foundation 
Data Upload Define Processes and Steps 
.
You define the sequence in which these steps should be executed and under which conditions.
Prerequisites
With this configuration, the upload process is initiated if the load manager has detected new data and created the corresponding process and step instances that PFC dispatches.
Process
Detailed technical explanation of the execution steps can be found in the section Interaction between the Load Manager and PFC.
