As some of you might remember from the Teched 09, SAP promised that in the near future SAP NWDS will be used as as tool for creating and maintaining SAP PI objects. It seems it has become a reality with SAP PI 7.3 at least for some objects. Please have a look at the early screens on how this works.
After opening NWDS you need to select the correct perspective.
Then you can log on to the ESR.
and this is the main view you can after opening.
As I mentioned before this tool does not replace the old ESR yet as there are still many objects missing. As of SP0 for 7.3 you can only create/change Data Types and Service Interfaces.
I need to admit that managing the changes it pretty easy and let me show you a few screenshots from it too:
a) maintaining a Data Type
b) maintaining a Service Interface
c) changing the properties of a Service Interface
d) adding new operations for a Service Interface
As you can see this is just a beginning but as SAP Product Management team says in the future we should have all functions from the old ESR moved to the new NWDS based user interface.
The screenshots were taken from SAP PI 7.3 SP0 release so it might be a subject to change – Please keep that in mind.
