Is WebDynpro ABAP a viable option?

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 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.

    Regards,

    Volker

      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 ...

      Regards,

      Volker

      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.
