During the openSAP course Developing and Extending SAP Fiori Elements Apps we got the question whether an OData Service as it was used in this course could be developed in other backend systems as well.

At the same time there was the ask for a feature comparison between the different ABAP Programming Models that have been delivered by SAP in the past and that are available now.

I had to admit that there is no such comparison / overview available. 

So I thought that this is a nice topic for another blog post.

If there is an important scenario feature that I have missed, please let me know, so that I can update my blog post accordingly.

Greenfield implementation

With greenfield implementation we mean scenarios where no legacy coding is called. Such scenarios are also called managed since in this case the underlying framework takes care of all create, update and delete requests and stores them in the database.

Brownfield implementation

With brownfield implementation we mean scenarios where existing legacy code such as a BAPI is being called by your service implementation in order to store the changed data in the database. Such scenarios are also called unmanaged. Another name for such scenarios are managed scenarios with a self implemented save.
