different component versions

[i045323]

In the following mention path, the component versions of the SAP systems are available.

System->Status->Component version.

In one SAP Systems i can see the value as SAP ECC 6.0.

In the other SAP system the value is SAP NetWeaver 2004s.

Can somebody explain me wht does they mean?

As far as i believe SAP ECC and Netweaver are two completely different layers.

SAP ECC is the application layer and obviously SAP NetWeaver 2004s is the technological layer.

I believed always the version of the technological platform is available in the Component version

section and not the version of ECC appication layer.

Somebody please clarify.

Thanks in advance.

Pramod.

Hi Matt,

Let me put it this way...

ERP system consists of the following components namely Netweaver, ECC, SEM, Cproject Suite.

Similary what does the netweaver stand alone system consist of??

Hi Pramod,

Are you sure you understand what NetWeaver is? A NetWeaver standalone system would consist of the Usage Type(s) that are installed for the role it is to play in the landscape -- BI, PI, Portal, DI, etc.

Perhaps you should take a look at the Master Guide - SAP NetWeaver available at http://service.sap.com/instguidesnw and/or the guide that I wrote How To Design a SAP NetWeaver Based System Landscape available here on SDN.

Hi Pramod

SAP ERP is based on SAP Netweaver. The software architectue is as follows (see also SAP ERP Master Guide from service.sap.com/erp-inst):

- SAP ERP includes different "own" installable units, such as SAP ECC, SAP SEM, or SAP XSS (Self Services). These are based on SAP NetWeaver 7.0, and supply the different application specific software components.

Example: SAP ECC requires a SAP Netweaver system with usage type AS ABAP.

- SAP ERP furthermore includes SAP NetWeaver installable units, such as for example SAP NW - EP Core, or SAP NW - Process Integration. These are required for using SAP ERP, but do not include own developments (They are "repackaged" from SAP Netweaver, including all needed tests, etc. "Repackaged" software units can be distinguised from SAP ERP components by means of the "SAP NW" in the name).

- SAP NetWeaver offers software units, which neither fall into above categories. Example: SAP NetWeaver Development Infrastructure

A SAP NetWeaver stand alone *** system*** is each system without additional applicaton installed (AS ABAP, BI, PI...)

- A SAP NetWeaver Standalone ***engine*** would be an additional installable software unit. They do not work as full-blown systems of SAP NetWeaver, but as standalone engines that provide specific (server) functionality in combination with one or more SAP NetWeaver systems. They are not part of a usage type. They do not run on AS ABAP or AS Java.

Example liveCache, or Search and Classification (TREX)
