My name is "Super Beginner"

Hello all !

I am working on what appears to be a Trial Version of Web Application Server 6.20

But I can hardly define what is finally a "Web Application Server".

I have to answer to very simple problematics, such as customers who want to make their classic SAP R/3 process available from the Internet (for exemple, making sales ordering possible from a webpage, consulting document flow in order to know at which step is the sales order...)

I have been said (by commercials :-[ )that SAP Netweaver would change my life and my way of apprehending SAP. For the moment, I must admit that I have only been quite lost and very frustrated.

Then I install a Mini WAS 6.20 ABAP Engine and I discover that Business Server Pages programming would very simply and correctly help me in my problematics. But many new questions have appeared...

1 - I develop BSP Applications in a SAP R/3 environment (transaction SE80). Where is Web Aplication Server in this ? And SAP Netweaver ? Do this concepts finally only deals with programming BSP Applications. I so often hear talking about Java and more... never seen them !

2 - When I seek deeper and deeper, I discover that I am developing on a ABAP Engine Kernel version 6.20 ... So ? BSP Programming is not possible on anterior version (upgrade from 4.5 & 4.6 to 6.20 obligatory ?)

3 - If I want to work on 4.6C version, what do I have to install in order to answer to my customer's requests ? Will only a developer studio be the solution.

I thank in advance all of you who will help me see clearly with answer or links that talks of WAS very pragmatically.

Best Regards ... and a happy new year !!!

    Sebastien,

    Let's make first a distinction between R/3 and Netweaver. R/3 is the classical ERP with all the modules like HR, PM, CM, FI, etc. Currently it's on version 4.7 aka Enterprise Edition. That is nowadays based on the same technology as the Web AS and thus one can make also BSP pages on it. It wouldn't do this though for security reasons. I would separate this and install a separate Web AS, which calls FMs via RFC.

    Then there is Netweaver, which is in fact a general name for specific product like Web AS, BW, XI, EP6 etc. see also service.sap.com/nw04. Currently we are on NW 04, which contains a new technology called webdynpro. It's a concept based on the M-V-C model and currently on Java. The next release of NW (05?) will have also Web Dynpro for ABAP. See also service.sap.com/webdynpro

    If you only want to let people use their standard SAP R/3 trx in their browser, the SAP gui for HTML is the thing for you. It's in fact based on ITS. More info on service.sap.com/sapgui.

    One can also put everything in a portal, then you need Enterprise Portal 6. See also service.sap.com/nw-ep

    Hope this clears things somewhat out. Pls don't hesitate to ask for further info.

    My two cents!

    1 - I develop BSP Applications in a SAP R/3 environment (transaction SE80). Where is Web Aplication Server in this ? And SAP Netweaver ? Do this concepts finally only deals with programming BSP Applications. I so often hear talking about Java and more... never seen them !

    If you go to transaction SICM you will see the Internet Connection Manager threads. ICM is what makes the difference between a standard application server and a web application server. All BSP requests are handled by ICM. This is only WebAS, NetWeaver has a lot more components.

    2 - When I seek deeper and deeper, I discover that I am developing on a ABAP Engine Kernel version 6.20 ... So ? BSP Programming is not possible on anterior version (upgrade from 4.5 & 4.6 to 6.20 obligatory ?)

    BSP is new since 610.

    3 - If I want to work on 4.6C version, what do I have to install in order to answer to my customer's requests ? Will only a developer studio be the solution.

    Yes, ITS and developer studio prior to 610/620. You can use Java connector to integrate java applications.

    If you have access to SAP Marketplace check the alias "webas".
