e DataFlow Object

Right-click on Data Flow Object

When creating the Dataflow object a transport request opens up.

Afterwards add a new or existing Datasource by drag and drop to the Details:

Double click on the entered Datasource leads to the following properties:

Select a Source System and if you want a copy from an existing or a proposal from an ODP connection

By clicking on the „NEXT“ button the Dataflow is shown – now it is possible to add any other object to the dataflow.

In this example an ADSO was added and filled with three InfoObjects

 

Now you created a persistent ADSO.

Activate the newly created ADSO. Create a connection between the newly created ADSO and the previously created Datasource

Now you’ll see a transformation and DTP creation is possible based on the connection.

Right-click on the transformation symbol and select “Create Transformation … “

Now you are able to create a transformation – Target and Source are filled automatically:

 

Here you are able to define all settings for the transformation as well as connect to the fields from the previous ADSO

 

In addition, if infoObjects are available in the source – they are automatically connected. Don’t forget to activate!

Same for the creation of the DTP. All DTP properties can be selected. You can see/select/change all the properties already known in BW.

Same process for the composite provider – drag and drop the composite provider, assign a name and create a connection to the ADSO.

 

It is also possible to add a comment for the specific selections within the dataflow. Click the one you want to comment on – go to the properties section and add documentation.

Conclusion

As you could experience, the Dataflow object is an easy way to model your intended dataflow. You can see all the different stages on one side in one place and do not have to click yourselves through your modelled dataflow, which can be difficult and time-consuming with two different tools either the Eclipse modelling tool and the SAP GUI.

Although it is a simple way to create a complete dataflow it does not replace process chains for loading data as it is moreover a graphical view of your model. For loading the data into your model you also need to create a process chain.

Finally I’ve put together some hints which will make your work easier:

  • Create Persistent Objects of ADSO, InfoSources, HCPR directly out of DataFlow Maintenance Screen
  • You can use Templates eg. Datasource or Infosource as templates and more.
  • When you have a SourceObject like an Infosource and a Target object like an ADSO, first create the connection in between before persisting the ADSO, then all fields/InfoObjects of the source are automatically taken into account for the DataModel of the Target.
  • Execution of DTP’s is possible
  • if you want to use DTP Monitor you have to execute the DTP in the DTP Maintenance Screen, from here the InPlace GUI is being called.
