Use

The persistent staging area (PSA), the entry layer for data in BI, has been changed in SAP NetWeaver 7.0. Previously, the PSA table was part of the transfer structure. You managed the PSA table in the Administrator Workbench in its own object tree. Now you manage the PSA table for the entry layer from the DataSource. The PSA table for the entry layer is generated when you activate the DataSource. In an object tree in the Data Warehousing Workbench, you choose the context menu option Manage to display a DataSource in PSA table management. You can display or delete data here. Alternatively, you can access PSA maintenance from the load process monitor. Therefore, the PSA tree is obsolete. You can no longer call the PSA tree from the Data Warehousing Workbench (DWB).

You use the Deletion of Requests from PSAprocess type to delete data for DataSources from the PSA tables in the entry layer. The system now supports multiple selections. You select objects in a dialog box for this purpose. The process type supports the deletion of requests from any number of PSA tables.

In PSA table maintenance, you can change the layout and save it as a display variant. You cannot transport the display variant. Furthermore, some of the symbols displaying the status of the individual records are now different to before.

If you are further processing data from the PSA table using a data transfer process, you can no longer use the Read PSA and Update Data Target process type. This is replaced by the Data Transfer Process process type. In the InfoPackage, data processing options are no longer available.
