SAP UI5 framework is getting rapid popularity among SAP web application developers.  Also, SAP has big plans on Fiori, the ready to use mobile web applications on SAP, built on SAP UI5 & SAP Gateway.

Moving from WebDynpro to UI5 development is a major shift in the development approach and skills. With this document, I wanted to highlight the key differences between these two commonly used UI frameworks from SAP.

    Great summary!!

    Personally I think the ‘Ability to customise and extend’ is the biggest advantage of UI5, no longer do we have to be restricted to the standard web dynpro controls and behaviours.

    Many thanks,

    Hi Sujesh

    Nice job.

    Java Webdynpro used to support mobile, guess still does.

    Could be handy to highlight the Browsers supported by Webdynpro as opposed to SAPUI5

    Thanks for sharing, for myself coming from WDPj I am a fan of SAPUI5 and as commented above by Jason, the extensibility is one of the key features.

    I like the blog. In fact one aspect seems to be missing: much of WDA is done today using FPM and this gives many possibilities for configuration, extensibility and componentization.

      I agree, I think FPM complements SAPUI5

      I just finished a big development on Hana and we chose ABAP FPM over SAPUI5 Gateway/XSOData as it was a better fit for the solution, WDA on its own wouldn’t have been.

    Hi Suresh,

    Thanks for sharing the comparison summary. But i have one query.

    Does SAPUI5 fit for creating ERP screens. Which is easy to create using WDA FPM.
