SAP Product

• SAP is not just SAP. The are a large number of
  SAP products (solutions), and it is rather
  confusing and difficult to see the big SAP
  picture. But here are the main SAP products
• SAP R/3 this is the SAP cornerstone, the real
  SAP if you like. R/3 has many different names,
  for example mySAP ERP, mySAP Business Suite, SAP
  all-in-one, SAP Enterprise. But it is all SAP R/3
  . To make it further complicated, these are also
  the so-called Industry Solutions (IS). This is
  also SAP R/3, but slightly modified for a
  particular Industry, for example Retail, Public
  Sector. Finally, there is SAP-all-in one. This is
  also SAP R/3 but in a pre-customized light
  version targeting small/medium sized companies.
• SAP CRM This is SAPs customer relationship
  management solution. CRM is an add-on product to
  SAP R/3, and it has its own user interface. CRM
  has some extra features which you don't find in
  SAPs SD module (sales and distribution).
• SAP SRM This is SAPs supplier releationship
  management solution. SRM is an add-on product to
  SAP R/3, and it is browser based. SRM has some
  extra features which you don't find in SAPs MM
  module (purchasing).

4. SAP BW This is SAPs Business Warehouse, or
information warehouse solution. BW is an add-on
product to SAP R/3, and it is basically a
relationship database. BW has its own browser
based user interface and it has some extra
features which you don't find in the standard SAP
R/3 information systems. 5. SAP APO This is
SAPs Advanced Planner and Optimizer solution. APO
is an add-on product to SAP R/3, and it is an
advanced sales, transport, production and
purchasing planner. APO has some extra features
which you don't find in SAPs SD, MM and PP
modules (sales, distribution, purchasing,
inventory, production). APO has its own user
interface. CRM, SRM, BW and APO are all fully
integrated with SAP R/3, but they have their own
special user interface and technical platform.

6. SAP NetWeaver This is the technical platform
that allows all the seperate SAP products to be
integrated. NetWeaver also integrates non-SAP
products, for example if you have a seperate
Warehouse or Production Planning system, and
wants to have it integrated with SAP. 7. SAP
Business One This is SAPs solution for small
companies. It is not SAP R/3, in fact SAP
Business One (SBO) is a completely different
software, originally not developed by SAP itself.
