SAP BW 7.4 Compatability with ERP Version

Hello ,

Is there any compatability matrix available for SAP BW system with ERP Version? I would like to know what is the minimum ERP system Version that could be connected to SAP BW 7.4 for data extraction from ERP.

Note: I have searched already few forums an it looks like interoperability Note- 1388258 - Version Interoperability within the SAP Business Suite

deals with SAP BW Hub system within Business suite.

Regards

Vijay
