asset procurement-tracking of assets

Please suggest solutions for the below scenarios. I will be very thankful to you for your precious suggestion.

Asset tracking:

How to effectively manage enterprise IT assets (hardware, software, and infrastructure devices), what IT assets you have, where they are located, who is using them, and how they are changing over time and how we can track them.

Also how to map Critical business issues that IT asset tracking including: license compliance and desktop standards enforcement.

Scenario-1:

Suppose if you procured 70 computers (assets) for your organization. 50 computers are assigned to 50 people across various locations. Balance of 20 computers are not assigned to anybody.

We have to map this scenario in SAP like:

1.How to track the quantity of assets procured.

2.How to track the quantity of assets assigned to particular people, where they are located and which computer is assigned to whom.

3.If we want to transfer computer from one location to other location how it will be mapped and how we can track (just like in an IT organization environment).

Scenario-2:

Suppose if you procured 50 router switch. Out of 50 ports, 30 ports are connected and 20 are free i.e., 30 ports are assigned to 30 users and 20 ports are not assigned to anybody.

We have to map this scenario in SAP like:

1.How to track which port is assigned to whom.

2.Track how many ports are connected and how many ports are not connected.

Scenario-3:

Suppose if you have taken 50 user license for SAP. Out of 50, 25 users login was given and they are utilizing their login. For other 25 no login was provided.

We have to map this scenario in SAP like:

1.How to track number of users utilizing user license and how many are not.
