Thus you can access simultaneously archive and database data using queries. This PBS solution is based on the SAP ADK process and is a pure software solution that can be seamlessly integrated with already-existing archive structures. It does not require any additional hardware. In the case of large volumes of data, we recommend constructing aggregates and indices. PBS provides special aggregate and indexing services for doing this. Moreover, you can archive, reload or update PSA tables via VirtualProviders in the ADK format. You also have the option to extract data from InfoCubes, DataStore objects, master data, texts, or any transparent tables from the BW system.
