Use

Real-time data acquisition supports tactical decision making. You use real-time data acquisition if you want to transfer data to BI at intervals that are more regular than scheduled data transfers (every hour or minute), and if you need to access this data in reporting frequently or regularly (several times a day, at least).

Real-time data acquisition supports operational reporting by allowing you to send data to the delta queue or PSA table in real time. You use a daemon to transfer DataStore objects that have been released for reporting to the ODS layer at frequent regular intervals. The data is stored persistently in BI.

You can use real-time data acquisition for DataSources in SAP source systems that support this, and for data that is transferred into BI using a Web service (push).

A daemon controls the transfer of data into the PSA table and its further posting into the DataStore object. In BI, InfoPackages are created for real-time data acquisition. These are scheduled using an assigned daemon and are executed at regular intervals. With certain data transfer processes for real-time data acquisition, the daemon takes on the further posting of data to DataStore objects from the PSA. As soon as data is successfully posted to the DataStore object, it is available for reporting. Refresh the query display in order to display the up-to-date data. In the query, a time stamp shows the age of the data.

The monitor for real-time data acquisition displays the available daemons and their status. Under the relevant DataSource, the system displays the InfoPackages and data transfer processes with requests that are assigned to each daemon. You can use the monitor to execute various functions for the daemon, DataSource, InfoPackage, data transfer process, and requests.

Effects on System Administration

DataSources in SAP source systems can support real-time data acquisition in source systems that have a BI Service API with Release SAP NetWeaver 7.0 (Plug-In-Basis 2005.1) or higher.
