PSA Transfer Method

Use when you want to load data into the Persistent Storage Area (PSA) before writing the data to the Operational Data Store (ODS) or InfoCube. When you use the PSA transfer method in SAP BI, the PowerCenter Integration Service writes data to SAP BI, which stores the data in a PSA. SAP BI updates or transforms the data after it has been stored in the PSA.

When you load data to SAP BI 7.3 using a 7.x DataSource, the transfer option is configured to load data to the PSA because the InfoPackage loads data only to the PSA.

When you load data using 3.x data sources, use one of the following PSA transfer options:

PSA and then into Data Targets.

Select this option when you want to store data in the PSA before you load the data to data targets such as an ODS, InfoCube, or InfoSource.

PSA and Data Targets in Parallel.

Select this option when you want to load data to the PSA and to data targets at the same time to achieve high performance.

Only PSA.

Select this option when you want to load data only to the PSA. You can also select the

Update Subsequently in Data Targets

option to load the data to data targets after you load the data to the PSA.

Data Targets Only.

Select this option when you want to load data only to data targets such as ODS, InfoCube, or InfoSource.

For optimal performance, configure the transfer option to load data to the PSA. After the source system loads the PSA, you can update the InfoCubes in SAP BW.
