External requirements from ERP to SRM with ExtendedClassic scenario for PPS

Hi all,

We are having SRM 7.01 system with ERP ehp4, and we have to do PPS ( Public sector Procurement) as part of our implementation,for that we need to activate Extended classic Scenario.

My question is whether we can have external requirements ( Material PR and Service PR) from ERP can be processed in the srm system.

Please help.
