Missing standard authorization roles in ERP

Hi,

I am going to implement authorization roles in SAP ECC 6.0 system, software component release 702. Only a few standard roles (starting with SAP_)can been seen in PFCG.

From where can I get standard roles for various modules? Did not yet find anywhere to download them from SAP net yet.

Or is it possible to switch on a certain business function to activate them?

Or any other way to get them?

BR,

Kjell
