Introduction

The open hub destination is the object that allows you to distribute data from a BI system to non-SAP data marts, analytical applications, and other applications. It ensures controlled distribution across multiple systems.

The open hub destination defines the target to which the data is transferred.

See the following figure outlines how the open hub destination is integrated into the data flow:

Use of Open Hub

Database tables (in the database for the BI system) and flat files can act as open hub destinations. You can extract the data from a database to non-SAP systems using APIs and a third-party tool.

Structure

The open hub destination contains all the information about a data target: the type of destination, the name of the flat file or database table and its properties, and the field list and its properties.

BI objects such as InfoCubes, DataStore Objects, InfoObjects (attributes or texts), and InfoSets can function as open hub data sources. Note that DataSources may not be used as the source.

Integration

You can use the data transfer process to update data to the open hub destination. This involves transforming the data. Not all rule types are available in the transformation for an open hub destination: Reading master data, time conversion, currency translation, and unit conversion are not available.

Creating Open Hub Destinations:

Once we select the Database Table, then the system automatically proposes the Technical name of the Table, it will starts with /BIC/OH<You’re Open Hub Name>

For Reference see SAP Help.

If we check the Deleting Data from Table option, every time the data will be deleted from Table i.e. before dumping new data into table, the old data will be deleted.

Note: Once you save and activate it, you can see the table in SE11 Tcode.

5. On the Field Definition tab page, you can see the fields list (from InfoCube).

Save and Activate.

Once you activate it then it will display the following message, if any errors are there then it will through the error message, here we don’t have any problem to generate table.

Some time if you don’t have authorizations to create a table then you will get the error message. So before creating the Open Hub Destination with Database table, please check the authorizations.

Now go to SE11 Tcode and give the table name and see the Table in the system.

Give table name and then click on Display button.

Step 2

Creating the Transformations.

Right click on our Open Hub Destination and then create Transformation between Open Hub Destination and InfoCube.

Give the Source and Target details like below. i.e. Our InfoCube Technical name and Open Hub Destination Technical name.

After giving the details then Press Enter.

In the following screen you can see the Transformations and mappings; the system will propose the mappings automatically.

Save and Activate.

Step 3

Creating Data Transfer Processes between InfoCube and Open Hub Destination.

Right click on our Open Hub Destination and Create DTP.

The system will take the default values, see the following screen.

Check the parameters in the above screen and then press Enter.

Save and Activate the DTP, you can see the different options in the Extraction Tab, we can select either Delta or Full. Here I selected Delta.

With delta we will get any new/modified records i.e. from InfoCube to Database Table.

See the options in Update Tab

Once it is Success, you can see the below screen with Green lights.

Go to SE11 Tcode and see the data in Table /BIC/OHZOP_TEST2
