3 Requests are transferred from a Flat File to the DataSource/ PSA and then to an InfoCube. The Data Transfer Process (DTP) should transfers all the new data from the PSA into the InfoCube via one DTP request.
It is recommended to configured the DTP with upload mode Delta. The deletion of the PSA data is necessary before each data load, if a Full DTP is used. A Full DTP extracts all Requests from the PSA regardless if the data has been already loaded or not. This means the Delta upload via a DTP from the DataSource (PSA) in the InfoCube is necessary, even if the data is loaded via a Full upload from the Source to the DataSource (PSA) by using an InfoPackage.

Step by Step:
- Loading 3 Requests into the PSA via Delta upload. In this case I started 3 times the same InfoPackage. Each upload Request consists of one record. The contents of the PSA after these 3 loads looks like: Picture 5
- Execute the Process Chain to load the data from the Flat File into the InfoCube. The DTP will extract the data from the Flat File (1 Request) and the existing PSA data (3 Requests) into the InfoCube. Contents of PSA after the execution of the process chain (data load): Picture 6
