Is WebDynpro ABAP a viable option?

[Former Member]

Hi all

Some generic questions, is WebDynpro ABAP a viable option? Can I suggest it to the customers? Is it a good practice to have UI and Business logic on the same server? Y are two strains of webdynpro one for ABAP and one for Java necessary?

I have also heard ESS MSS runs on both ABAP and Java WebDynpro. Y is SAP complicating the skillset required to deal with Business Packages? Please give me links or direct answers as suitable. Thank you all.

Hi,

see the answer of Stephan Ritter and Rüdiger Kretschmer in .

Additional infos can be found here:

Thanks for the answers they were really good but still diplomatic. One question that still stings me is how is an enterprise on road to eSOA if they have WDA framework?

When people talk about composition environment it is all about Java. The next step to CE is BPP, the goal of SAP!!

How can I utilise the CAF using WDA?

How open is WDA to other third party solutions based on XMLs and WebServices?

When it comes to ESS MSS we now need additional skillset of WDA! ESS MSS in ECC 7.0 is expected to be totally on WDA. Then is the ESS MSS a composite?

An organisation might have all their UI on WDJ but ESS MSS alone on WDA. It creates unnecessary confusion to have to two strains of WD in an enterprise.

In any case ESS MSS is to be hosted on EP which mandates the Java server, then what is the need of writing applications in WDA? And if I want to include a service call in my UI is WDA capable? Sometimes I feel it might make us directionless but then that is my opinion.

Your suggestions pls.

Hi vln!

some generic answers:

WebDynpro for ABAP of course is a good choice when writing UIs for SAP business logic. I see no problem when UI and business logic reside on the same server but you shopuld take care not to put business logic into the UI part; that is clearly separate UI (that is WebDynpro for ABAP) and Business Logic (that is ABAP Objects classes and/or function modules).

If you only need WebDynpro for ABAP to access SAP logic you do not need WebDynpro fro Java part.

ESS and MSS are NOT developed in WebDynpro for ABAP, but more or less completey in WebDynpro for Java. That is you need a Portal with a Java Stack where trhe ESS and MSS UIs run and you need the ABAP HR stack where the business logic resides.

Hope this was helpful for you.

The travel management of ERP 6.0_EHP2 is on WDA!!

ESS MSS on ECC 7.0 will be on WDA!!

Hi LNV!

What the hell is ECC 7.0???

As far as I know there is a ECC600 (what we have - new name is ERP 6.0) and then there will come Extension Sets and then for a very long time nothing new ...

Where did you get this information?

Concerning WDJ / WDA / CAF:

CAF is definitely on SAP Netweaver 7.1 CE a Java product; if your company or your customers want to use the full bandwidth of features/tools SAP offers, then you will need Java and ABAP people. There are some restrictions when you want to integrate WDA applications in Composite Applications.

Whether this strategy born in Walldrof is a good or bad ... that's another story.

Hi Volker

All that I have written is based on help.sap.com. And here is the link (Go to WDJ in Travel manangement and look at constraints).

<a href="http://help.sap.com/erp2005_ehp_02/helpdata/en/46/51f0e994b85e40e10000000a11466f/frameset.htm">ECC 7.0 WDA</a>

And yes you are right, ECC 6.00 is enhanced using EHPs -> enhancement package. I am talking abt EHP 2.

I am using CAF on NW 7.0 and hence the concern. And when I say composite my UI is essentially calling faceless services. That alone gives me the power to orchestrate processes quickly. The only reason I put these questions is because the same are coming out of my customers too!! And I need to give a concrete answer on the UI paradigm as well. Though I have made up my mind the future releases of ESS MSS is troubling to hear. Thank you for the patience shown in answering my questions.

Hi LNV!

One last personal statement from me: In my opinion SAP goes "back to the roots" step-by-step, that is back from Java to ABAP, at least for application functionality.

If you have a look at eRecruiting (BSP/WDA) and CRM current release 5.0/5.1 and future release 7.0 (BSP/WebUI) and the ERP UIs (e.g. create sales order) released with EHP2 (WDA) and ESS/MSS you have found (WDA/BSP), then this may make you thoughtfully ... I am sure there are completely contrary opinions in SDN ...
