Open Hub Service The Open Hub service enables you to distribute data from an SAP BW system into external data marts, analytical applications, and other applications. With this, you can ensure controlled distribution using several systems. The central object for the export of data is the InfoSpoke. Using this, you can define the object from which the data comes and into which target it is transferred. Through the Open Hub service, SAP BW becomes the hub of an enterprise data warehouse. The distribution of data becomes clear through central monitoring from the distribution status in the BW system.

How to get to it The transaction code for Open Hub is RSBO, or from the Administration Workbench select Tools->Open Hub Service

BW object such as InfoCubes, ODS objects, or InfoObjects can act as open hub data sources. You can select database tables or flat files as open hub destinations. Both a full and delta modes are also available as the extraction mode.

Components The main component of open hub is an InfoSpoke. All you have to do to extract data from BW using open hub service is create and activate an InfoSpoke for each BW object. I have provided a series of screen-print that show just how easy it is to create an InfoSpoke.

Creating InfoSpoke In the main menu of the Administrator Workbench, choose Tools _ Open Hub Service. Create InfoSpoke Enter a technical name for your InfoSpoke. Choose Create InfoSpoke.

In the following dialog box, enter a description for your InfoSpoke. You can also specify a template here.

General Tab On the General tab page, select a data source. You can choose from an InfoCube, ODS object or InfoObject (attributes or texts). Select a destination. You can also enter the technical name of a destination that you are about to create.

Finished page should look something like this

Destination Tab Choose the Destination tab page and enter a description.

You have an option to select a Logical Target System. Or send it to a file on Application Server or on your local disk.

InfoObject Tab From the InfoObjects tab page, select the InfoObjects that need to be transferred. In doing so, the available fields are displayed in the right half of the screen, and you can transfer them into the left half of the screen by using the arrow keys.

Selection Tab From the Selection tab page, you can restrict the selected fields even further. As a restriction, only simple selections of single values and intervals are possible.

Activation Choose Activate InfoSpoke .

It is a good idea after you have activated the InfoSpoke to exit the transaction and enter back into it by choosing:

Extraction Choose Start Extraction . A status log is displayed.

A status log is displayed.

If you do not want to start extraction straight away, that is, you want to schedule it, you need to include the InfoSpoke into a process chain. The result is that you have extracted data from an open hub data source into a database table or a flat CSV file.

Output The process creates two files: The one that starts with S_ is the structure file and the other is the data file.

Five Main Points Openness to extract data from BW. All BW data objects are supported for extraction. Delta tracking for each target system. Scheduling and central monitoring.

SAP BW can serve as an enterprise information

hub (EDW) and feed data to any downstream system.
