When CI is retired asset substate is set to empty instead of disposed.

[Rajat Singahl]

What is the idea of OOB Asset CI Install Status Mapping for Configuration Item status Retired.

Write now the value of Asset substate is empty, So what is the good practice to update the Asset substate when CI is retired.

[Mark Manders]

If you have logic or reporting requirements that need for you to set the substate on asset. you can customize it. 

If you want to know the idea behind it, you will need to reach out to ServiceNow (NowSupport) to ask their reasoning.

[Rajat Singahl]

when Ci is retired I want Asset state to be retired and substate to be disposed. Updating the OOB CI mapping is the best practice or not is what I want to understand

[Mark Manders]

Yes. That's the best way to go, because if ServiceNow does anything with it on any future update, it will show up in your skipped changes.
