ASK - Support & Benefit from Annual License Maintenance

Hi there,

trying to get clear and objective about benefit, customer's right, and support will get while pay annual license maintenance for SAP Business one.

here my question:

1. Underlying of policy AML, which control all policy and term condition about AML.

2. What is benefit, support right as customer when pay fee AML

3. Who is responsible to deliver support to us?

4. If there is update or patch, do the customer need to check periodically and install by them selves?

or this is our partner's responsibility?

perhaps someone from SAP Support can give me detail. Yes I know I may ask to our partner. Still not satisfy enough until I get answer from SAP itself.

thank you
