Enterprise Portal Usage

Hi,

Currently I am the process of understanding SAP NetWeaver architecture. I have following quries on the same.

1. How does WebDynPro and Enterprise Portal is interlinked? Does Enterprise Portal development happens with DynPro as presentation layer? or else just by using EP is it possible to develop applications?

2. Where does CRM Server, APO Server etc fits in the NetWeaver architecture?. How does EP communicate with them?

3. Do we need to download EP component seperately or else it would come along with WAS ?

Any help on this would be highly appriciated.

Regards,

Arun.

    1. EP can use WebDynpro application. See https://www.sdn.sap.com/sdn/pilot.sdn?page=eL_NW.htm for more info.

    If you know java, it's fairly easy to develop custom EP java iviews

    2. Again see presentations on Netweaver overview https://www.sdn.sap.com/sdn/pilot.sdn?page=eL_NW.htm

    Think CRM servers are linked through SSO from the portal

    3. The EP must be downloaded separately (but comes bundle with the WAS)

      1. As far as I understand(I am no expert at this) Netweaver is the common word for the whole refrigirator.

      WebDynpro is one way to present data, but when developed is totally independent of EP. However, it can be integrated.

      EP can use WebDynPro, but almost all in-the-box components are similar to java Servlets (just a bit more event oriented framework on top of this, as well as access to services etc.)

      2. Well generally the WAS only sends the url back to the browser along with the sap logon ticket, and then the browser contacts the CRM system. The EP is an application on the WAS

      e.g

      Browser -> WAS -> EP

      and back

      EP -> WAS -> Browser (with SAP logon ticket)

      Browser->WAS2 -> CRM (think CRM runs on WAS as well)

      Therfore it is important that the CRM and EP are in the same DNS domain (SAP logon ticket is a cookie)
