Introduction:
Using new functionality of Real-time Data Acquisition (RDA) with the Net Weaver (BI) 2004s system we can
now load transactional data into SAP BI system every single minute. If your business is demanding real-time
data in SAP BI, you should start exploring RDA.
The source system for RDA could be SAP System or it could be any non-SAP system. SAP is providing most
of the Standard Data Sources as real-time enabled.
Here is the difference between the Standard Data Acquisition and Real Time Data Acquisition.

We can transfer the data from the source system to the entry layer of the BI (PSA) in two ways:
Using a Web service:
You use the Web service to write the data from the source into the PSA. The transfer of data is controlled
externally, without a request from BI. Only an InfoPackage (for full upload) is required to determine specific
parameters for real-time data acquisition.
Using a service API:
Data from an SAP source system can be loaded into the PSA using an InfoPackage created specifically for
this purpose. This is triggered when the delta queue in the source system requests data. You have to
simulate the initialization of the delta process for the DataSource beforehand.

Daemon:
It is a background process that processes the Info Packages and data transfer processes assigned to it at
regular intervals.
Controlling the Daemon Processes: Transaction RSRDA
A daemon is: a system process that performs a specific task at regular intervals. The SAP NetWeaver BI
daemon performs three steps (depending on the chosen scenario):
1. It triggers the service API (SAPI) to transfer data using an InfoPackage for real-time data acquisition
to the PSA.
2. It tracks the status of the data transfer from the source system.
3. It triggers the update of the data to the DataStore object using the DTP for real-time data acquisition.
The successful execution of the three steps is reproduced in a control table (confirmation table).

Prerequisites:


The DataSource must support real-time data acquisition.



One of the possible properties of Web service DataSources and DataSources from SAP source
systems is the option of supporting real-time data acquisition. In the DataSource maintenance, the
Extraction tabs under Real-Time displays this characteristic. DataSources from SAP source systems
can be used for real-time data acquisition if the following prerequisites are met:
1. BI Content DataSources must support real-time data acquisition.
2. Generic DataSources must have set the real-time-enabled indicator in the settings for the
generic delta.
3. Keep in mind that DataSources from SAP source systems can support real-time data
acquisition only as of source systems with the BI service API level SAP NetWeaver 2004s
(Plug-In Basis 2005.1). For real-time data acquisition, also keep in mind that you can only
use Web service DataSources that you have specified using the (new) DataSource
maintenance in BI.



You use the transformation between PSA and DataStore object and update the data from the PSA to
the DataStore object with the data transfer process.

Procedure:
DataSource Creation in Source System: Create the generic data source in R/3 system with ‘Real Time
Enable’ as shown in the following screen.

To make Standard DataSource ‘Real Time Enable’ we need change it through ROOSOURCE table, for that
we need to have Access key.
Replicate the Generic DataSource under respective Application Component and activate this DataSource.
Make sure that this DataSource is ‘Real Time Data Acquisition Supported ‘. This can be verified in the
following screen.

Create an InfoPackage for the above DataSource with ‘Initialize Delta Process’ .
Create one DSO (Standard) which will be updated by Real Time Data Acquisition.
Create Transformation for the above created DSO.
Create DTP for the above created transformation with DTP Type ‘Real Time Data Acquisition’ as shown in
the following screen.

For above created DTP processing mode is ‘Processing Mode for Real Time Data Package’ as shown in
the following screen.

Create an InfoPackage for the RDA with ‘Real Time Data Time Acquisition InfoPack‘check box checked as
shown in the following screen.

In the processing tab of InfoPackage we enter the maximum time (Threshold value) for each request to
open. Once that limit is cross RDA creates new request. The data is updated into data target ASAP it comes
from Source System (~ 1 min), even though request will be open to take new record.

Go to Schedule tab in the InfoPackage Screen and ‘Assign’. It will go to RDA monitor screen (T-code
RSRDA)

Create Daemon with following information.

The above created InfoPackege will come under ‘Unassigned Nodes’.

Assign the created Daemon to the

Info Package.

Now the InfoPackage will come under the assigned Daemon.
Assign the DTP (With technical name) as shown in the in the following screen.

Start the Daemon.

Once you start the Daemon, you can check Open Request in PSA of DataSource or in RDA Monitor under
InfoPackage also.
