Submitted by: Administrator

R 3 Means ( Three tier architechture ) 1st Tier ( R1 )
launched at the time of SAP inception with five x ibm
employees , later on 2 nd & 3 rd tier had come in the form
of advanced . Now latest is My SAP CRM.

R 3 actual Nomeneclature is ( ECC - Enterprenuer Central
Component )

CRM acts as a central server attached to its external
systems such as ( BIW , ECC & Third party systems , etc ).

Eg : If a client has already had installed SAP ECC ( R3 )
and wants to upgrade with SAP CRM , in this scenario , we
have to integrate or fetch some data related to Sales ,
Pricing Conditions etc thru R 3 / ECC .

This is done thru middle ware concept ( connectivity ) ,
for which you should posses knowledge on the middleware
concepts
