Webdynpro ABAP in HCP

Hello,

Could anyone please give some comment for the webdynpro abap vs Cloud Portal ?

I am sorry if this question is not matured enough, any inputs would be highly useful.

(1) How do Webdynpro ABAP applications continue onto HANA Cloud Platform ? What would be the changes in them ? Example, Transportation Management module has extensive Webdynpro ABAP applications. If we implement the latest version of TM (we do not have TM module right now) and we opt for HCP then we do have to continue working on webdynpro abap and all these applications cannot be converted to SAP UI5 / Web IDE. Am I right ?

(2) Do these applications have fiori tiles ? are they suitable to run in fiori or do we continue them in classic on-premise portal ? What is the advantage of running them on HCP and how do we do that?

(3) If we integrate the Webdynpro ABAP applications into the Launchpad, what happens after that? Do they run on-premise or on HCP? what is the advantage of that?

(4) What exactly is the TM Collaboration portal coming up with the latest, yet to release version?

(5) What is the best reading or reference material related to the future of webdynpro abap applications in TM module w.r.t. HCP / Collaboration portal / Wed IDE / SAP UI5 / Fiori against the current conventional classical e-portal.

thanks in advance for any comments / inputs.

Hi Bhakti,

(1) SAP TM is an on-premise solution. Therefore I suspect that if SAP product management will ever offer this in the cloud (I am not even aware if it is already available on S4/HANA Cloud Edition - not a TM specialist) they will port the solution to a modern UI technology such as SAPUI5. Even so, nowadays there are several applications written in webdynpro and ITS that make up the collections of web applications that are available to on-premise systems and that can be launched via Fiori Launchpad for seamless integration and provide the same UI experience and simmilar look & feel themming, etc.

(2) Yes, Webdynpro apps can be integrated into a Fiori launchpad and be mexied with Fiori Apps. For a complete list of apps that can be integrated into Fiori Launchpad, please take a look at this page. So you could, in theory, completely replace your NW-Portal installation - provided that you are comfortable with such replacement. If there isn't a catalog of tiles for TM apps, you could create your own custom. I see that there are tiles ready for SAP Smart Business 1.0 for transportation management.

(3) You can have a hybrid scenario (which involves SCP + On-Prem System). Meaning: your ERP system (be it ECC 6.0, S4/HANA, etc) can be connected to a GW system. Then your Cloud Portal will connect via Connector to this GW system. If you don't wish to access the Fiori Launchpad as a Cloud Portal, but rather want to access the Fiori Launchpad that is On-Premise, you could. This is available on your GW box. Another scenario is the one in which you could use Fiori Cloud Edition. The scenario will be simpler to deploy as all applications are made ready for you on a "front end server" provided by SAP. Nevertheless, you still need to have a GW system on-premise connected to your ERP for the RFC backend communication and Odata.

(4) ...

(5) ... Not sure how to answer 4 and 5. Perhaps you are better off with several questions on the community. There is just too many topics to discuss with different skills/knowledge be be addressed by single contributors.

Regards,
Ivan

Hi Ivan,

thanks a lot for your response and all the detailed explanation.

I am attending this open sap course and getting some answers.

https://open.sap.com/courses/portal1

My primary objective is to find the effect of cloud platform on webdynpro abap applications.

Could you please give some more guidance on 'what is the advantage of running webdynpro applications on cloud and why shouldn't we continue running it on premise enterprise portal ?'

many thanks,

bhakti.

Q: "what is the advantage of running webdynpro applications on cloud"?

A: You protect your investment on an application that is already tested and is fully accepted by your audience. And at the same time you allow users to approach a newer technology for launching their apps (Fiori Launchpad). Not to mention that it gives you the ability to use newer applications built on the Fiori Paradigm and mix them together. Once you are ready to reinvest on applications that were built on webdynpro, than you could think of rewriting them for SAPUI5 or keep them - it is up to you.

Q: "why shouldn't we continue running it on premise enterprise portal ?"

A: Enterprise Portal is, in my experience, hard to maintain for some folks as it is using Java underneath and most technical people aren't familiar with it - thus they cannot solve complex issues when they rise. However, there are certain features provided by NW Enterprise Portal that aren't available or cannot be easily replaced by Fiori Launchpad (Cloud or On-Premise). So you should carefully think how you use your NW-EP. If it is just a simple application launcher used for SSO and Inbox Approvals, I don't see a compelling reason to keep using it - but that's my own opinion.

Regards,
Ivan

Hi Ivan,

We are yet to move on HCP and considering moving from e-portal to HCP against continuing on e-portal. Most like we will go on to HCP so it is very much valid that we make use of the investment and run WDA on HCP along with other modules and applications all put together. Regarding launching of the WDA applications though, we could also launch it from Fiori Launchpad and still run it on e-portal instead of HCP right?

As far a maintenance is concerned we are expert at WDA and dealing with it since many years. its the HCP and UI5 that is new (we are on it, nevertheless)

Its not a simple inbox approval and there are many complex screens in the WDA. I assumed that the screens and layouts would not be effected if we run the same thing either on e-portal or HCP. Where should I look for the features that are on e-portal but not seen on Fiori / HCP?

thanks again,

bhakti

Q: "we could also launch it from Fiori Launchpad and still run it on e-portal instead of HCP right?"

A: I believe that your case NW-EP and Fiori Launchpad can be considered as "shell" launchers for SAP applications that are running on your ERP. Thus, it doesn't matter who is calling the WDA url. You could even create a bookmark page and launch these apps from there. So the answer is yes, you can launch WDA apps from both Fiori Launchpad and ERP - simultaneously.

NOTE: I would recommend starting with an on-premise installation of NW-GW (you will need it anyway) which comes with Fiori Launchpad so you start trying it out. You will also need a reverse proxy (I recommend SAP Web Dispatcher) in front of both to avoid cross-site-scripting (souces include: ERP, GW and HANA XS Classic).

Q: "Where should I look for the features that are on e-portal but not seen on Fiori / HCP?"

A: I don't recall seeing any feature comparison out there. But basically everything that is not related to application launching is not available in the Cloud Portal Service (Fiori Launchpad on HCP). You could create your own static content mixed with applications in the cloud portal service - but it would be very different in what you could do with NW-EP-KM. So it is far from being a KM system. On HCP you will not find most cool features of KM (like scheduled publishing) nor COLL features. All of these would need to be developed by you as either a microservice in CF or as an application in Neo (probably Java).

NOTE: Look for the UX Best Practices documentation and figure out yourself (or hire a consulting agency - recommended) how to deploy Fiori Apps on your landscape. Start integrating standard apps from the Fiori Catalog with your custom built WDA apps. Once you are comfortable with it, it will be the time to move to HCP. (BTW: HCP has been re-branded as SCP - which stands for SAP Cloud Platform).

Ivan

Hello Ivan,

thank you for the detailed information.

When you say - " basically everything that is not related to application launching is not available in the Cloud Portal Service (Fiori Launchpad on HCP)." - I am not sure what you mean by 'everything not related to application launching' . Perhaps that is not what I need either. I should have been more specific in my question. When you said earlier "there are certain features provided by NW Enterprise Portal that aren't available or cannot be easily replaced by Fiori Launchpad (Cloud or On-Premise)." , what are these features? if I have a complex webdynpro application with many screens and internal functionalities , it should not matter if I am running it on my premise enterprise portal or the SCP. Am I right (sorry if its a dumb question)

thank you

bhakti
