The PSA is the entry layer for data in BI. The data is updated to PSA tables that were generated for active DataSources during the load process. The PSA is managed with a DataSource.
The previous technology of the PSA was oriented to the transfer structure. The PSA table is generated for an active transfer structure in this case. The PSA as a standalone application is managed in an object tree of the Administrator Workbench.
You can still use this technology when your data model is based on the previously available objects and rules (DataSource 3.x, transfer rule 3.x, update rule 3.x). However, we recommend that you use the concepts for DataSources and transformations available after SAP NetWeaver 2004s, which includes using the new technology of the PSA.
