R/3 Enterprise on Web AS 6.40

Does anyone know if R/3 Enterprise will run on Web AS 6.40. I just heard a presentation where we informed that only Web AS 6.20 or 6.30 was compatible. However, I thought the Web AS was downward compatible. Also, 6.40 is in ramp-up right now, if it can't be used for Enterprise, what is the ramp-up for? I can't see that SAP would expect customers to run NetWeaver components on 6.40 and then have a separate Web AS for Enterprise. These are very confusing times.

Hello Jeff,

as always a kernel update (such is 6.40) is not automativcally available for any R/3 version. Just that in former times we did not deliver technology without apps and threrefore there was no reason to give you a new version of the technology before the appropriate R/3 was finished. Though you will first be able to get WebAS 6.40 and then there will an update of R/3.

As this has changed, you now do get WebAS before R/3 runs on it- and, er - the name of the ERP changes to mySAP ERP...

Just to make sure I understand the relationship between the application, the kernel and the Web AS; does the kernel version correspond to the same version number of Web Application Server - are they the same thing? SAP Note 662523 states that SAP has planned to release kernel 6.40 as a downward-compatible kernel for kernels 6.10 and 6.20. Does that mean that anything that runs on Web AS 6.10 or 6.20 will also run on Web AS 6.40? Or are the Web AS and the kernel separate, so you can have Web AS 6.20 running kernel 6.40? Hopefully this will clear up my confusion.

Thanks,

Jeff Mathieson

Hi Jeff,

the differentiation is that there is a kernel, that is contained in WebAS, but on top of this there is the WebAS ABAP environment, which not necessarily is compatible to your R/3.

So downward compatibility means you could run the 6.40 kernel under R/3, but <b>this means that you won't get the slightest functionality of 6.40</b> in your ABAP programs.

Does this make it clear?
