PDP and Central Contracts in SRM 7.01

Hi Sap Gurus,

Could you please share the differences in configuration setting for Plan Driven Procurement in SRM 7.01.

As per my knowledge the BADI used for PDP in SRM 7.01 is different and configuration settings are also minimized when compared to SRM5.0

Also please share some market place links or documents relating to PDP and central contracts in SRM 7.01

Thanks in advance
