Relased SAP Versions Till Now

Hi,
Differences are
1)SAP 4.7 has a more structured approach as compared to SAP 4.6C from a
technical perspective. It is based on mySAP.com technology, which is actually
the Web Application Server 6.2C. This not only includes SAP Basis Technologies
with their latest advancements but also the new features of SAP Web AS 6.20.
2) SAP 4.7 is more structured even from a functional perspective as this version
has been developed after functional and infrastructure developments of earlier
SAP R/3 4.6C.
3) In SAP 4.7 the functional and infrastructure developments are made on separate
levels. The functional developments are made in the Enterprise Extensions and
infrastructure developments are made in the Enterprise Core unlike SAP 4.6C in
which both the developments take place within the systems.
4) SAP in its Web AS has additional enhancements in the form of package concept,global parameterization with business configuration sets, Unicode complianceand accessibility that are not present in 4.6C.
5) SAP 4.7 Core supports the above-mentioned enhancements that SAP 4.6C doesnot.
6) SAP 4.7 unlike 4.6C has Enterprise Extensions that can be separately deployedand have their own releases.
