How OS Version is getting populated via SCCM?

[Saurav Bhardwa2]

We have an SCCM setup in our ServiceNow instance. I am unable to find the mapping for the "OS Version"
attribute on the computer class in ServiceNow. It is adding values like 10.0.22631, 10.0.18363, etc., but I am not sure if that mapping is configured out-of-the-box somewhere. Could you please let me know where in SCCM these values are generally mapped?

1) Go to IH ETL. 

2)open the computer ETL

3)Check the class mapping 

4)See the attributes which are mapped to os version.
