how to create SAP and Raw structures in SAP system

Hi Experts,

I am from PI back ground, and new to AIF.

I have gone through to AIF cookbook, but still I need some more clarity of how to create the below.

1. SAP and RAW structures

2. Value Mapping

3. Actions

4. Checks

I have gone through SDN, did not find a right blog. Could you help we to walk through the aforementioned with an example.

Thank you
