NWDI Migration for Entire CE Landscape

Former Member
0 Kudos

Dear Experts,

We have planned NWDI rollout for our entire Composition Environment (CE) Landscape.

This means that, we will be doing migration of all the developments that are done in Local Environment (till date) to the Central NWDI Environment.

We are in CE 7.1 (EhP1, SP01)

So far everything has worked according to our plan.

Our CE Landscape leverages all the different varieties of Development Components (e.g. WebDynpro, Dictionary, EJB, Library, BPM/BRM etcu2026)

We have everything in place now as belowu2026

- For each project, we have separate Tracks created and ready.

- For all these Tracks, relevant DTR-Workspaces (Inactive & Active workspaces of DEVELOPMENT & CONSOLIDATION runtime systems are all created successfully)

- Also the relevant CBS-Buildspaces are also created successfully.

- All projects are in Consistent state in the Local environment.

- The all Local DCs were copied to the Track SC successfully.

- Project structures of all the DCs are created successfully.

- Build, Deployment and Testing in the development system is also succeeded.

- Entire source code of each project is now wrapped inside multiple activities.

From this point, I need clarifications on several things as explained belowu2026

Scenario 1:

1. We Check-In, Activate and Release all the activities containing the entire source code.

2. But, we do not import these activities into Consolidation system.

3. Now, we make some modification in the DC again that will be wrapped inside another isolated activity.

4. This time we Check-In, Activate and Release AS WELL AS Import this activity into consolidation system.

5. And then assemble and attach it to the CTS Transport Request created in Solution Manager.

6. And take it forward to the Quality server for deployment.

7. When we test the application in QA Server, the last modifications that were wrapped in the activity are not

reflected.

8. But, In Development system the changes are very well reflected.

Now, as explained in above scenario the process is partial, as DTR Consolidation Work spaces (Inactive/Active) both were completely empty for the first time, because as mentioned in step-2 we did not import activity in CONS. But as explained in Step-4, when the latest modifications are imported in CONS and then after assembly state transported to Quality system the changes are not reflected.

Scenario 2:

1. Now, the pending activities containing entire source code (as explained in point number 2 in scenario 1) is imported and assembled.

2. And then the SCA is attached to the CTS Transport Request created in Solution Manager.

3. Forward to the Quality server for deployment.

4. Now, the changes are reflecting properly in Quality server.

From the above explained 2 scenario, it is clear that we canu2019t escape from the step of importing the activities containing the entire source code into consolidation system, as a onetime course of action, when we are rolling out NWDI.

Our main Concern here is to make sure that, redeployment of all the applications present in the entire landscape again in production (that will be coming via the route CONS>Assembly>QA) should not create any anomalous results, as we donu2019t want to take any chances with production system.

Is there any way by which we can start using NWDI without redeployment of all the applications present in the entire landscape again in production?

Please help me clear off these clouds of uncertainty.

Dear All,

Thank you so much for your valuable inputs.

I have got confirmation from SAP on this.

It is not possible to only assemble parts of changes which already been

imported to CONS system. There is no workaround on that. Therefore that

means if you want to make ALL changes reflected on your QA server, ALL

changes must be imported to CONS and all assembled afterwards, and

therefore it is not possible to only deploy partial changes to the

production server.

Check the SAP Note 877029

Check the link below for NWDI migration:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70ee5ab2-8d7a-2c10-d88b-dbe2fdf66...

Scenario 1:

Did you happen to check the CBS WebUI whether the requests are getting queued in Consolidation?

If so restart the CBS Service and see if the requests are imported or not.

Hope this helps.

Cheers-

Pramod

Dear Pramod,

Thank you for your reply.

The SAP Note and PDF link that you have provided is all about system copy.

Please don't misinterpret my message; we are not looking for system copy at all.

Let me reframe my requirement.

We are migrating the way of Java development procedure from classical way of working in Local Development environment to the NWDI leveraged centralized environment.

As it will facilitate the centralized source code management and version control which is currently not present in our business.

But for achieving this, we have found out that we will need to deploy every single application that is present in our landscape once again in Production system (As we canu2019t escape from the step of importing the entire source code (of each application specific to track) into consolidation system for the first time during rollout, and then during assembly step the .SCA will be constructed based on the source code present in the consolidation active workspace)

From the business point of you our stakeholders will not agree to this particular scenario, as it literally means that age old applications will also go through this process and it may also be the case where the latest source code (being present in NWDI workspaces) may not be the same as what is there in production system, so we donu2019t want to face any such consequences.

I hope I have made myself clear.

Hi SHreyas,

That document or note talks about Upgrading the SP level so got confused.

For your scenario try looking up http://service.sap.com/instguides

It have all the documents needed for the upgrade.

I Couldn't find for 7.2 but there is one for 7.3 may be it follows the same procedure.

Hope this helps.
