请问SAP NetWeaver 和 SAP R⼀3 或 ECC 的区别

Netweaver是SAP公司新一代产品运行平台，一般看到的所谓的SAP2005,MySAP等都是运行于这个平台上的。SAP R/3和ECC是差不多的东西，所谓的ECC，就是Enterprise Central Component——企业核心组件，那么所谓的ECC都有哪些呢？R/3里的SD/MM/PP/FI-CO这几大传统模块都属于ECC的范畴，所以说SAP R/3和ECC差不多。

R3 is a general kernel names, like 22D, 30F, 31H, 40B, 45B, 46C, 4.7 (R3E).It came out from R2 (2 Tires). R3 is 3 tires(DB/AP/frontend). all MM/PP/SD/FI/CO modules will running on top of it. ECC is new set of SAP package and it's running on new Netweaver kernelECC 5.0 = ERP2004 running Netweaver 2004ECC 6.0 = ERP2005 running NetWeaver 2004sPortal is part of Netweaver Portal 6.0 is part ofNetweaver 2004Portal 7.0 is part of Netweaver 2004s(same as BI 7.0 )
