Master Data in SRM 7.01

Hi Sap Gurus,

In SRM 5.0 master data comes into SRM from ECC in BDOC format and the GR and IV will be replicated to ECC in IDOC format with the help of ALE/IDOC's

Does this same in SRM 7.01????

will the GR and IV replicated to ECC in IDOC format with ALE/IDOCs or we use XI/PI???

Thanks in advance
