SAP's compatibility with Windows Server 2003

Hello,

I had a question about SAP's compatibility with Windows Server 2003.

In Product Availability Matrix and also in all documentation(SAP with Windows), SAP says OS platform supported as "Windows Server 2003".

However, Windows Server 2003 can be :

1) Windows Server 2003 Standard Edition

2) Windows Server 2003 Enterprise Edition

3) Windows Server 2003 Datacenter Edition

So does SAP supports all these Windows Server 2003 Editions?

If yes, how to decide which one to use?

Let me know your views.

Thanks a lot,

Nirav.
