Hi All,

 

We are using OOB 'Windows OS-server' pattern for windows server discovery.
we found that it is giving first priority to retrieve and populate baseboard serial number for windows server.
However customer wants to update "system" serial number(win32_ComputerSystemProduct.IdentifiyingNumber) for windows server in CMDB instead of baseboard serial number.
to achieve this, we wanted to create extension to override with system serial number instead of baseboard serial number.

could you guys help on how to create extension  for override and populate with system serial number for windows servers?

Hello @pavan garige ,

You can check out the ServiceNow "Service Mapping Fundamentals On Demand" course.

There is a dedicated course on extending a pattern.
