From version 9 of the CLM/Sourcing application you can integrate with both the ECC and the SRM systems..
CLM/Sourcing to ECC - use to create "Purchase orders, Outline agreements, scheduling agreemnts"
CLM/Sourcing to SRM - use to create "Central Contacts" and this can then be distributed to the ECC systems connected to SRM (if ECC is connected to SRM).
