Introduction: In our BI System there are several numbers of reports which are highly complex and very sensitive with respect to data being fetched, which helps in making decisions on the basis of data of your transactional system. Sometimes single change in the transactional data can help us to make any of our changes in important decisions.

Using new functionality of Real-time Data Acquisition (RDA) we can now load data into SAP BI system every time it gets updated in the system.

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. Over here I am implementing this whole process with the help of Web services but you can choose any of the options present in the system.

Step-by-Step Solution

Create Web service Data source in BI system. For this select web service from the source system and click on create.



It will show u the following options. Put a logical system name, source system name and the type and release as shown.

When you double click on the logical system name, it will take you to the specific data source that is data source for WEB.

Then create an application component and a specific data source for that logical system.



In the fields tab specify the fields which you want to give in your DSO.

In my DSO there were 6 fields. You can specify which fields are there in your DSO. Save and activate your data source.

When you successfully activate your data source then in the extraction tab ‘Function Module’ and ‘Web Service’ automatically gets generated.



Now you need to create a DSO with all those fields which are being used in the data source.

Right click on DSO and create transformation for that DSO. In the object type give the data source name and the required information.



Now create Infopackage for that data source

In the processing tab, we enter the maximum time for each request to open. Once the limit exceeds, RDA creates new request.



In the schedule tab we try to assign demon. Click on the Assign Demon tab and you will be taken to the RDA monitor tab.

In this screen you can see that for a particular data source your daemon has been allocated to unassigned nodes automatically.



You need to assign it manually from unassigned node to a new daemon. This is basically required to start the daemon.

Give a daemon id for that. Over here 11 daemons are already created so I gave it number 12. But you need to number it accordingly to the daemons present in the system.



Assign the DTP for newly created Daemon.

The following screen appears in which you need to give the DTP name which you want to assign.



Then click on start daemon with all Infopackage

Once you start the daemon you can check the request which is open of data load in PSA table of data source

Now you need to create a RFC to get this data from PSA table to the DSO via DTP. For that create a RFC ZTEST_RFC and the code is as below.

This is actually the import parameters which are taken for the RFC to be created. In the associated type you see the function module name that was generated automatically when we activated the data source.



If you double click on the associated type, then you reach the line type screen.

Then if you double click on the line type you will see the structure of the DSO in the components tab.



This is the coding for the RFC.

This function module which is used in between RFC “/BIC/CQZDS_DSO00002000” is that function module which was automatically generated when we activated the data source.

Here we have only used the fields which were used in the DSO and passed the fields some values via hard coding and then collected those values in the internal table IT_data and passed that itab in the function module.



Now execute this RFC

It will show the screen after executing the RFC.

The record comes to PSA and it will show the open request for DTP.

Click on start demon by right clicking on Daemon name.



Now when you start its status will become green

You can see the open request in the RDA monitor of DTP.

Now you can check the data in DSO which is updated in the DSO.

Now you can close the request in the Daemon.



Now you can stop the daemon although it will continuously run and when the request comes then it will load the data.
