Master agreement Hierarchy functionalities

Hi,

I had a few questions on master agreement hierarchy function on ver 9.

1. How would the contract document stored on the parent flow down to the child agreements. Or there isn't any such functionality. If not is the expectation to maintain contracts at each level of the hierarchy?

2. Any limitation on the the parent and/or child agreement being interfaced to SAP SRM as a central contract?

Thanks
